Abstract

Recently, several geographic routing strategies considering a mobile sink node have been proposed for wireless sensor networks. A mobile sink node should frequently update its location information in source nodes for successfully receiving data from the latter. However, frequent location updates from the mobile sink node may result in the consumption of too many network resources. In this paper, we propose an efficient multiagent-based location update strategy for a mobile sink node in wireless sensor networks. Agent nodes that are located on the path between the source node and the mobile sink node contain the location information of the mobile sink node. In addition, the agent nodes are changed dynamically to maintain the approximate shortest path between the source node and the mobile sink nodes. We analyze the performance of the proposed scheme by performing simulation using Qualnet 5.0.
