    Opis:
    Extensive utilization of WSN is the reason of advancement of numerous routing protocols. The Late advances in WSN now witness the expanded enthusiasm for the potential use in applications like Environmental, Military, Space Exploration, Health (Scanning), Vehicular Movement, disaster management, Mechanical anxiety levels of appended objects, battle field observation and so forth. Sensors are required to be remotely conveyed in unattended situations. Propels in WSN innovation has given the accessibility of little and minimal effort sensor hubs with a capacity of sensing different sorts of physical and natural environment conditions, wireless communication and data processing. Assortment of sensing capacities results in bounty of application areas. However, the attributes of WSN require more powerful strategies for data forwarding. The sensor hubs in WSN have a constrained transmission range, and their handling and capacity abilities and as well as their energy assets are also restricted. Routing protocols for WSN are in charge of keeping up the routes in the network system and need to guarantee dependable multi-hop communication under these conditions. Routing as one key innovations of wireless sensor systems has now turned into a hot examination on the grounds that the uses of WSN are all over the place, it is unthinkable that there is a routing protocol suitable for all applications. In this paper, we give an overview of routing issues routing protocols for Wireless Sensor Network.

    Opis:
    Vehicular Ad-hoc network (VANET) is an exacting form of Mobile Ad-hoc Network (MANET) where the vehicles are act as nodes. Due to high mobility of nodes, high partitioned network and also dynamic changing routing protocols, the routing in Vanet is dispute one. The routing protocols functions should depends on the internal and external characteristics of VANET such as nodes mobility, road topology and obstacles which block the signal. A routing protocol is used to find the route between the nodes to communicate each other. The particular route to be selected by routing protocol. The routers have the information about the network which is directly connected to it. The routing protocol first forward the information to the immediate neighbor node, then it forward the information throughout the network. In VANET the routing protocol are classify based on topology, position of vehicle, cluster based vehicle, broadcast based routing and geocast based routing. This article explains the topology based routing protocol, especially reactive routing protocol which is a part of the topology based routing protocol.

    Opis:
    Wireless Sensor Networks have played a great role in various application domains like environmental tracking for precision agriculture, structural health monitoring, patient health monitoring, intrusion detection, earthquake or volcano prediction and industrial monitoring etc. The major design issues to be dealt in Wireless sensor networks (WSNs) are its resource constraint nature, limited network lifetime and scalability. The most stringent of all is energy consumption and battery life which actually limits the network lifetime. This paper presents various energy aware location based routing protocols and in depth comparison based on various characteristics such as routing selection method, data aggregation, routing metrics, periodic message type, scalability, energy efficiency, robustness, event/query based and strengths.

    Opis:
    The below work is done to address the things like how fast can information be collected from a wireless sensor network organized as tree using realistic simulation models under the many-to-one communication paradigm known as converge cast. We first consider time scheduling on a single frequency channel with the aim of minimizing the number of time slots required to complete a converge cast. Next, we combine scheduling with transmission power control to mitigate the effects of interference, and show that while power control helps in reducing the schedule length under a single frequency, scheduling transmissions using multiple frequencies is more efficient. To this end, we construct degree-constrained spanning trees and capacitated minimal spanning trees, and show significant improvement in scheduling performance over different deployment densities. Lastly, we evaluate the impact of different interference and channel models on the schedule length.

    Opis:
    A Mobile ad hoc network is a continuously self-forming, infrastructure-less network of mobile devices connected without wire. Routing protocols for Mobile ad hoc network are responsible for maintaining the routes in the network and have to ensure the reliable multi-hop communication. Many existing routing protocol approaches measures the performance of ad hoc networks. In ad hoc network faces some challenges like Qos, network congestion, data collision. Using clustering in MANET to avoid packet transmission delay, network congestion and packet loss, etc. This paper aims to provide a comprehensive study of the routing protocol performance in clustered ad hoc network.

    Opis:
    Wireless Sensor Networks (WSNs) are networks that consist of sensors which are randomly deployed in inaccessible area to gathering data and transfer it to user or base station. The most important matters considered in sensor networks are efficient utilization of energy, network lifetime, and environmental conditions changes. To provide the communication facilities within the network a routing protocol is used. There are many techniques used to route data in sensor networks, clustering based is one of most common techniques used, cluster based routing protocols can be classified to proactive and reactive protocol depending on how source finds a route to destination. This paper is aim to study and compare the two mechanisms in cluster based routing by discuss different characteristics in each mechanism, and also analyzed the performance of two mechanisms by take two exemplar protocols LEACH and TEEN from proactive and reactive mechanism respectively in order to compare the performance in same scenario and simulation parameters.

    Opis:
    Mobile Ad-Hoc Network is an wireless systems it supports mobile communication in a network. MANETs are affected by several security attacks but it affects the features that are like open medium, dynamical changes in topology, lack of central monitoring and management and it not obtain the clear defence mechanism to MANETs. To prevent or detect malicious nodes launching collaborative wormhole attacks is a challenge. The existing system designs a dynamic source routing (DSR)-based routing mechanism, but it is also referred to as the cooperative bait detection scheme (CBDS) to detect the wormhole attacks effectively. Here we describes the various wormhole attacks and prevention methods for wormhole attack.
