Comparative analysis of proactive & reactive protocols for cluster based routing algorithms in WSNs

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.
