Manju Bala, Lalit Awasthi . On Proficiency of HEED Protocol with Heterogeneity for Wireless Sensor Networks with BS and Nodes Mobility. International Journal of Applied Information Systems. 2, 7 ( May 2012), 58-62. DOI=http:/ijais12-450369
In this paper, the enhancement of HEED protocol to support mobility in both homogenous and heterogeneous network [Homogeneous HEED (H-HEED), two-, three-level heterogeneous (2H-HHED & 3H-HEED) and multi-level heterogeneous HEED (MH-HEED)] has been presented. Here, we have examined the performance of HEED, 2H-HEED, 3H-HEED and MH-HEED with random mobility in wireless sensor network in terms of stability, energy efficiency, lifetime and throughput. The results establish that the MH-HEED in sensor network proved to be superior because of the enhancement in the performance metrics like: stability, lifetime and throughput (data packets transmitted to BS) with the random mobility of BS. The network performance is dominating in terms of stability, throughput and energy efficiency if 3H-HEED protocol is used and it is useful for habitat monitoring and other similar applications. The overall performance of the network substantially improved in case of BS mobility.
