Distributed Optimal Power and Rate Control in Wireless Sensor Networks
With the rapid development of wireless sensor networks, reducing energy consumption is becoming one of the important factors to extend node lifetime, and it is necessary to adjust the launching power of each node because of the limited energy available to the sensor nodes in the networks. This paper proposes a power and rate control model based on the network utility maximization (NUM) framewor...
متن کاملDistributed Optimal Rate-Reliability-Lifetime Tradeoff in Wireless Sensor Networks
The transmission rate, delivery reliability and network lifetime are three fundamental but conflicting design objectives in energy-constrained wireless sensor networks. In this paper, we address the optimal rate-reliability-lifetime tradeoff with link capacity constraint, reliability constraint and energy constraint. By introducing the weight parameters, we combine the objectives at rate, relia...
متن کاملOptimal Power Allocation for Distributed Detection in Wireless Sensor Networks
In distributed detection systems with wireless sensor networks, communication between sensors and a fusion center is not perfect due to interference and limited communication power of the sensors to combat noise. The problem of optimizing detection performance with imperfect communication between the sensors and the fusion center over wireless channels brings a new challenge to distributed dete...
متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
متن کاملDistributed algorithms for transmission power control in wireless sensor networks
Two algorithms for dynamically adjusting transmission power level on a per-node basis have been evaluated using a simulative approach. Network lifetime, convergence speed as well as resulting network connectivity have been obtained for these two algorithms using a particular indoor sensor environment. The network lifetime metrics of these two local algorithms are also benchmarked against power ...
