Energy consumption and network connectivity are two of the important research issues that are yet to be resolved in mobile ad hoc networks (MANETs). As taken advantage of in static networks, reliable topology control algorithms are also considered to be a good approach for mobile networks. However, a more adequate evaluation of these algorithms regarding mobility is still needed. In this paper, we...
To achieve efficient broadcasting with low interference and low energy consumption, each node optimizes its transmission power. In a tree-based topology, the message of node u can be overheard by nodes which are in the region of transmission radius of node u but not in a logical neighborhood of u. Therefore, some protocols have been proposed to reduce energy consumption by using overhearing. Since...
In wireless ad hoc sensor networks (WASNs), a crucial issue is to reduce power consumption while satisfying some key network properties. In this paper, we propose a fault-tolerant topology control that optimizes the lifetime of the network at a given degree k of connectivity by minimizing power consumption. Our topology control is fully distributed and uses a model-based transmission power adaptation...
Topology Control and energy saving is one of the most important challenges in wireless sensor networks because of Special characteristics of these networks such as limited transmission range, low bandwidth, limited power resource and the impossibility of recharging. In this paper, k-fault tolerant clustering topology control algorithm is presented. This algorithm named QoS-based clustering topology...
