A Tabu Search Heuristic for Point Coverage, Sink Location, and Data Routing in Wireless Sensor Networks
نویسندگان
چکیده
The point coverage, sink location and data routing problems are considered in an integrated way and two new mixed integer programming formulations are proposed. As these models are computationally difficult to solve, a nested solution procedure is proposed. The best sensor locations are sought by tabu search in the top level. Given the sensor locations, a simpler formulation is obtained and the remaining problem, which is the sink location and data routing can be solved efficiently. Experimental results indicate that the performance of the nested solution approach is very good.

متن کاملAn Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
