In this paper, we develop a heuristic algorithm to construct an efficient object tracking in wireless sensor networks (WSNs).Such wireless sensor network has to be designed to achieve efficient object tracking for given arbitrary topology of wireless sensor networks.We consider the two-way object moving frequency of each pair of sensor nodes and link transmission cost.This problem is formulated as 0/1 integerprogramming problem.A Lagrangean Relaxationbased (LR-based) heuristic algorithm is proposed for solving the optimization problem.The experimental results showed that the proposed algorithm gets a near optimization in the efficient object tracking.Furthermore, the algorithm is very efficient and scalable in terms of the solution time.
