The fault-tolerant character of WSN protocols and applications that do not assume completely reliable systems legitimize undervolting - a highly efficient energy management technique where the supply voltage is set below the minimum specifications. As has been shown in earlier work, by using thereliable IdealVolting undervolting scheme the lifetime of WSN applications can be increased significantly...
In last few years, there has been a growing interest in the area of Wireless Sensor Networks (WSNs). Now a day's WSNs are being deployed in large sensing areas for real life applications. As sensor networks has limited and non-rechargeable energy resources, prolonging the lifetime of WSNs is a great issue. Some sensor nodes of comparatively high energy can be used (i.e. making the WSNs heterogeneous...
In wireless sensor networks (WSNs), asynchronous sleep-wake scheduling protocols can be used to significantly reduce energy consumption without incurring the communication overhead for clock synchronization needed for synchronous sleep-wake scheduling protocols. However, these savings could come at a significant cost in delay performance. Recently, researchers have attempted to exploit the inherent...
To prolong the lifespan of wireless sensor networks, while working with the limited battery life of each sensor node, energy efficiency and energy balance are basic considerations. To achieve balanced energy consumption, non-uniform distribution methods are proposed as a network infrastructure modeling scheme. However, node transmission distance, which has significant relevance with energy efficiency,...
