Maximizing Lifetime for Data Aggregation in Wireless Sensor Networks
This paper studies energy efficient routing for data aggregation in wireless sensor networks. Our goal is to maximize the lifetime of the network, given the energy constraint on each sensor node. Using linear programming (LP) formulation, we model this problem as a multicommodity flow problem, where a commodity represents the data generated from a sensor node and delivered to a base station. A ...
متن کاملClustering Based Lifetime Maximizing Aggregation Tree for Wireless Sensor Networks
Energy efficiency is the most important issue in all facets of wireless sensor networks (WSNs) operations because of the limited and non-replenish able energy supply. Data aggregation mechanism is one of the possible solutions to prolong the life time of sensor nodes and on the other hand it also helps in eliminating the data redundancy and improving the accuracy of information gathering, is es...
متن کاملan efficient protocol for data aggregation in wireless sensor networks
sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...
متن کاملMaximizing α-Lifetime for Wireless Sensor Networks
In energy constrained wireless sensor networks, it is very important to conserve energy and prolong network lifetime while ensuring proper operations of the network. In this paper, we investigate how to maximize the α-lifetime of wireless sensor networks, where α-lifetime is defined as the time duration during which at least α portion of the surveillance region is covered. We first present, giv...
متن کاملPerformance Analysis of Lifetime Maximizing Trees for Data Aggregation in Wireless Sensor Networks
In this paper the performance of the proposed DLMT and CLMT algorithms are compared. These proposed algorithms tend to extend the node lifetime. Decentralized lifetime maximizing tree(DLMT) features in nodes with higher energy to be chosen as data aggregating parents while Centralized Lifetime Maximizing Tree(CLMT) features with the identification of the bottleneck node to collect data in a cen...
