Distributed Algorithms for Maximizing the Lifetime of WSNs with Heterogeneity for Adjustable Sensing Ranges
Samayveer Singh, Satish Chand, Bijendra Kumar · Electrical engineering research · 2013
In this paper, we study the impact of heterogeneity on homogeneous protocols. Most of the protocols for increasing the lifetime of wireless sensor networks are designed for homogeneous networks. The load balancing protocol with adjustable sensing range (ALBPS) and deterministic energy efficient protocol with adjustable sensing range (ADEEPS), are two important homogeneous protocols. In this work, we incorporate 3-level heterogeneity to the ALBPS and ADEEPS and the resultant protocols are named as heterogeneous load balancing protocol with adjustable sensing range (HALBPS) and heterogeneous deterministic energy efficient protocol with adjustable sensing range (HADEEPS), respectively. We compare the performance of the ALBPS and ADEEPS protocols with that of the HALBPS and HADEEPS protocols. The simulation results indicate that the heterogeneous protocols further prolong the network lifetime.
