Anycast Routing Algorithm for Wireless Sensor Networks Based on Zone-Disjoint Scheme
摘要
Abstract
Anycast technique can significantly balance data flow and energy consumption in Wireless Sensor Networks (WSN). Most previous research works adopt path-disjoint or node-disjoint scheme to search anycast paths, but it cannot solve the transmission collision problem caused by the hidden terminal problem, thus bring much extra retransmission energy consumption. For this problem,an anycast routing algorithm for WSN based on zone-disjoint scheme is proposed(ZDAR). In the algorithm,we select anycast paths one by one in order of their neighbor nodes' impact factors (the degree that the neighbor nodes participate in other anycast paths) and ensure that the paths will not collide with each other,in contrast to zone-disjoint routing algorithms based on shortest path first(SPF)scheme,ZDAR algorithm can find more zone-disjoint anycast paths. In comparison with node-disjoint scheme and zone-disjoint routing scheme based on SPF, simulation results show that the performance of ZDAR algorithm is better in term of the composite indicator about both total energy consumption and energy balance,thus improving the network lifetime.关键词
