TAILIEUCHUNG - Node deployment and the impact of relay nodes in wireless sensor network

In pre-determined deployment, location of the nodes are specified. Most commonly used cell structure is Regular Hexagonal Cell Architecture. Here we will discuss the concept of relay nodes and its impact in sensor nodes. | ISSN:2249-5789 Rudranath Mitra et al, International Journal of Computer Science & Communication Networks,Vol 2(3), 358-363 Node Deployment and the Impact of Relay Nodes in Wireless Sensor Network Rudranath Mitra1 , Diya Nandy2 Department of Information Technology Heritage Institute of Technology Anandapur,. diya1nandy@ Abstract more processing power than the other neighbouring nodes and so their battery power also drains out faster than the other nodes causing possible shortening of network lifetime. Therefore, deployment of sensor nodes has serious impact on network lifetime. The nature of deployment of sensor node depends on the type of sensors, application and the environment where the network will operate. Deployment of sensor nodes can be random or pre-determined. In random deployment nodes are randomly deployed generally in an inaccessible terrain. For example, in the application domain of disaster recovery or in forest fire detection sensors are generally dropped by helicopter in random manner[2]. In pre-determined deployment, the locations of the nodes are specified. It is mainly used in indoor applications. For example, manual placing of sensor nodes in pre-determined locations is done to monitor manufacturing plants, detection of corrosions and overstressed beams in large old buildings etc. In WSN we try to deploy a minimum no. of relay nodes so that between every pair of sensor nodes there is a connecting path and such that each hop of the path is no longer than the common transmission range of the nodes. To tackle the random deployment issue from a lifetime perspective, we must account for the biased energy consumption rate (BECR) phenomenon, described as follows. Consider a heterogeneous wireless sensor network composed of relay nodes (RNs) and sensor nodes (SNs).Traffic originates at sensor nodes(SNs) and is send to the base station via the relay nodes(RNs). In a single hop heterogeneous WSN, where
