One issue with sensor networks is that there are bottleneck nodes, which relay more data than others. Generally, bottleneck nodes are located near the sink in sensor networks. However, bottleneck nodes may not always be located near the sink when sensor node distribution is not uniformly. In such a situation, the conventional approach using multiple sinks depletes the batteries of bottleneck nodes earlier than those of nodes near the sink. As a result, the network lifetime is shortened. This paper proposes a scheme that takes into account bottleneck nodes for a wireless sensor network with multiple sinks in order to improve the network lifetime. We refer to this scheme as DCAM (DispersiveCast of Packets to Avoid bottleneck nodes in using Multiple sinks). In DCAM, the sink finds bottleneck nodes and each node sends its sensing data to multiple sinks so that the load of the bottleneck nodes can be balanced. We evaluate DCAM using computer simulations with several network topologies and show that DCAM prolongs the network lifetime compared with the conventional scheme.
