In this paper, we propose a set of heuristics to be used within greedy algorithms to build connected dominating sets (CDSs). These algorithms depends on a heuristic and we show that the selection of such heuristic is fundamental to optimizing system operation, both in terms of energy consumption and data transmission. Based on some parameters such as the node's degree, the distances between nodes...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
We study the problem of transmission-side diversity and routing in a static wireless network. It is assumed that each node in the network is equipped with a single omnidirectional antenna and that multiple nodes are allowed to coordinate their transmissions in order to obtain energy savings. We derive analytical results for achievable energy savings for both line and grid network topologies. It is...
