Abstract


A Wireless Sensor Network (WSN) contains special distributed autonomous devices called sensor nodes in order to keep track of physical and ecological conditions for instance temperature, strain, vibration, noise, moisture, motion or toxins and also to coordinately pass the information from the network to particular location. Routing in WSN is very challenging because of features that separate these kinds of networks from other wireless networks. To extend network lifetime creating efficient routing protocols is crucial. Despite the fact that WSN are generally intended for surveillance as well as reporting activities, because they are application based so a single routing protocol is not suitable for all applications regarding WSN. This contrast of routing protocols uncovers the important capabilities that must be considered while creating and analyzing new routing protocols regarding sensor systems. This work thoroughly investigates key Hierarchical and Location based routing protocols using Network Simulator 2 (NS2) and evaluates the performance of these protocols against some performance metrics that helps to select performance wise best protocol.
