Recently, wireless sensor networks (WSNs) drew the attention of the research community, driven by a wealth of theoretical and practical challenges. Wireless sensor networks are formed by connected sensors that each have the ability to collect, process, and store environmental information as well as communicate with others via inter-sensor wireless communication. The many-to-one communication pattern...
Recently wireless sensor networks (WSNs) are used to monitor the physical environment through the large number of battery-powered sensor nodes. Because it is difficult to change or recharge batteries, nodes are spend large amounts of time in a low-power "sleep" mode generally. WSNs have sparked numerous research interests in sleeping methods to schedule nodes' activities. In this paper,...
In this paper, a new non-cooperative power control algorithm for wireless sensor networks is presented to choice the appropriate transmission power. Due to reduce packet collisions and increase good put, the algorithm can effectively control transmission power of the nodes and prolong network lifetime efficiency to satisfy the maximum requirement of network utility. The existing of Nash equilibrium...
In recent years power control becomes one of research hotspots in wireless sensor networks to reduce total energy consumption in packet interference and improve channel spatial reuse. For the random power control approach, the wireless module of a sensor node picks up one stochastic power value between the minimum and the maximum to send data packet. Connectivity of the random power control approach...
