As the energy becomes the most valuable resource in the wireless sensor networks, to prolong the lifetime of the network, energy-a-ware protocols are proposed which use the energy minimization techniques and multi-hop paths. However, multi-hop paths and Complex calculations at nodes introduce delay and processing overhead. Providing energy-efficiency becomes a scalability problem. Scalabilh y Of a routing protocol for Wireless sensor networks is Mainly affected by the topological changes and by the number of sensor nodes in the network. In large scale networks with a large number of sensor nodes, multiple-sinks (gatewqvs) should be used to provide scalability. In this paper, a novel stateless energy-efficient routing technique, Stateless Weight Routing with Multiple Sinks (MS-SWR), is introduced for wireless sensor networks. MS-SWR requires 770 local/global topological information. Proper y of being stateless avoids the communication overhead and reduces the calculations to minimum. In MS-SWR, reliability, is provided b y v using multiple paths which also reduces the delay to minimum for the time-critical real-time traffic The pe formance evaluation of the proposed technique shows that MS-SWR is scalable for large scale wireless sensor networks with Multiple Sinks.
