A Hybrid Routing Algorithm in Wireless Sensor Networks

As sensor networks have severe energy constraints and energy-efficient dissemination, redundant low-rate data, and many-to-one flows, this paper propose a routing algorithm :HRA. This algorithm is based on node-centric routing load balancing algorithm, position-centric routing on trajectories, and data-centric data aggregation. It can improve network performance: routing, querying, discovery. After our comprehensive analyzing, we found that the algorithm is effective prolong network existent , reduces transfer amount, lower cost.
