Load Balanced Geographic Routing in the Vicinity of Holes in WSNs
○Phi Le Nguyen・Ji Yusheng(NII, Sokendai)
Geographic routing is a popular approach in wireless sensor networks, which can achieve a near-optimal routing path in networks without holes (i.e., regions without working sensors). With the occurrence of holes, however, geographic routing faces the problems of load imbalance and routing path enlargement. In this paper, we introduce a novel approach in dealing with routing in the vicinity of holes which is the first to target and solve both the load imbalance and path enlargement problems. The experiment results show that our proposed protocol outperforms the existing schemes in several performance factors, including routing path stretch and load balancing.
