A new wireless sensor network middleware for collaborative object tracking

Due to the overall complexity of wireless sensor networks, programming sensor networks poses considerable impediments and makes application development nontrivial. A middleware layer is a novel approach to glue together the operating systems, network stacks, and applications. In this paper, a new wireless sensor network middleware for collaborative object tracking has been proposed, which is consisted of three related algorithms: the node selection algorithm, the object management algorithm, and the session maintenance algorithm. The simulation results using ns-2 show that in a wireless sensor network using IEEE 802.15.4 protocol, the system with the proposed middleware has better performance than system without the proposed middleware.
