Multi-attribute decision making for data-centric routing in wireless sensor network

Recent data-centric routing protocols in wireless sensor network usually aim to pursue either the minimum energy consumption (the maximum network lifetime), or the minimum delay time, but can not achieve a good balance. To address this issue, an efficient routing algorithm is proposed, in which multiple routing information are taken into consideration for routing decision making in a quick and accurate way. And a general distance metric is defined for processing both exact and fuzzy data. As a general framework, this method can provide various routing decisions on the choice of different attributes to meet diverse routing requirements. Simulations show the suitability and efficiency of the proposed routing scheme.
