Secure data collection is an important problem in wireless sensor networks. Different approaches have been proposed. One of them is overhearing. We investigate the problem of constructing a shortest path overhearing tree with the maximum lifetime. We propose three approaches. The first one is a polynomial-time heuristic. The second one uses ILP (Integer Linear Programming) to iteratively find a monitoring...
The main contribution of this paper is the design and test of a simple, reliable, and energy efficient routing scheme for sensor networks that successfully meets the goal of network longevity, and that demonstrates satisfactory robustness and network lifetime. The proposed routing algorithm allows a child sensor node dynamically searches for a new reliable parent node with more residual energy and...
Sensing connectivity and sensor coverage in sensor networks are two fundamental issues, which have been extensively addressed in the literature. The reliability of wireless sensor networks (WSN) depends on both network connectivity and sensing coverage. Most existing work on sensing coverage has focused on the full coverage problem. However, in some application scenarios, full coverage is either impossible...
