Comparative Analysis of Energy Efficient Routing Protocol for Wireless Sensor Network
A wireless sensor network is consists of hundreds or thousands of nodes that are densely deployed in a large geographical area. These nodes are commonly used for continuously monitoring applications. Also these sensor nodes have small batteries. The energy consumption is the main issue in WSN's. The efficient routing protocol should minimize the energy consumption. In this paper, the authors compare base station assisted hierarchical cluster based routing with LEACH and also replace data aggregation from set up phase. Instead of a single cluster head group of cluster heads in a cluster manages the network. On rotation basis, a group of cluster heads member receives data from the neighbor nodes and transmits the aggregated data to distance base station.
