Design of Multi Chain Power Efficient Gathering for Sensor Information System Using Sink Mobility

Recent advances in MEMS technology had given rise to the sensor devices capable of being operated in any type of environment for monitoring and observing some phenomenon. In spite of having the broad perspective to be used in a variety of applications, sensor nodes lacks in their limited energy resources. The hierarchical routing protocols provide a way to preserve individual node energy by reducing the communication between the nodes and the sink directly. In this work, various protocols are studied and analyzed for energy consumption of nodes with concern to the network life. The performance of Low-Energy Adaptive Clustering Hierarchy (LEACH) and multi-chain Power Efficient Gathering for Sensor Information System(PEGASIS) are analyzed and compared to have a look at how much they contribute to the network lifetime extension. After their comparative analysis, some improvement in multi-chain PEGASIS is presented with the concept of sink mobility resulting in 300% more network lifetime than LEACH and 150% more operative rounds than in PEGASIS.
