An accurate, energy efficient strategy for target tracking in wireless sensor networks is proposed. An extended Kalman filter algorithm is used to improve tracking quality and reduce communication between sensors. At any time, only one sensor, called the leader, processes and tracks the target. A two phase technique is used to determine the leader. The first phase establishes the leader when a target...
A new clustering approach, termed Distributed Energy Efficient clustering Protocol (DEEP), is proposed for wireless sensor networks. Using a non-iterative cluster formation operation, the protocol spends an extremely low overhead energy compared to the existing protocols and terminates faster than the energy-expensive iterative processes. The distributed head election algorithm guarantees that the...
In this paper, a new protocol termed CoopXLM that integrates cooperative communication and Cross-Layer Module (XLM) is created and examined via simulation. CoopXLM modifies XLM by allowing multiple cooperative nodes to participate in receiver-based contention. Although there is increased energy consumption for processing, simulation results indicate that across all duty cycles there is an average...
In this article the LEACH (low energy adaptive clustering hierarchy) in the homogeneous wireless sensor networks (WSNs) was considered and a new protocol with an approach toward promoting LEACH was introduced. In the new protocol which is called LELE (leader election with load balancing energy), the major work was how to elect the leader which was done through changing the sensor's energy, LELE protocol...
In tactical applications of wireless sensor networks (WSNs), such as intruder detection, tracking, and patrol operations, there tend to be multiple, mobile end-users who work amidst the sensors in the field to which data from individual sensors must be directly delivered. Efficient data dissemination in such networks is a challenging problem, since sensors with detections must be able to identify...
