Sentry Selection in Wireless Networks
Let P be a Poisson process of intensity one in the infinite plane R2. We surround each point x ofP by the open disc of radius r centred at x. Now let Sn be a fixed disc of area n, and let Cr(Sn) be the set of discs which intersect Sn. Write E r for the event that Cr(Sn) is a k-cover of Sn, and F r for the event that Cr(Sn) may be partitioned into k disjoint single covers of Sn. We prove that P(...
متن کاملSentry-Based Power Management in Wireless Sensor Networks
This paper presents a sentry-based approach to power management in wireless sensor networks for applications such as intruder detection and tracking. To minimize average power consumption while maintaining sufficient node density for coarse sensing, nodes are partitioned dynamically into two sets: sentries and non-sentries. Sentry nodes provide sufficient coverage for continuous monitoring and ...
متن کاملSentry selection in sensor networks: theory and algorithms
We study the geometric aspects of the sentry selection problem for a sensor network with randomly distributed sensors each of which covers a small disc. The problem is to partition the sensors into a predetermined number of groups, so that, for each group, the sensing regions of the sensors in that group together cover the region of interest. After presenting some theoretical results, we includ...
متن کاملPerformance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
متن کاملAn Efficient Cluster Head Selection Algorithm for Wireless Sensor Networks Using Fuzzy Inference Systems
An efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. The implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. According to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses Fuzzy Inference Systems to select cluster head. The alg...
