On-line disjoint path routing for network capacity maximization in energy-constrained ad hoc networks
March 2007
Ad Hoc Networks , Volume 5 Issue 2
Publisher: Elsevier Science Publishers B. V.
Additional Information:full citation, abstract, references, index terms
Bibliometrics:  Downloads (6 Weeks): n/a,   Downloads (12 Months): n/a,   Downloads (Overall): n/a,    Citation Count: 1

In this paper we consider on-line disjoint path routing in energy-constrained ad hoc networks. The objective is to maximize the network capacity, i.e. maximize the number of messages routed successfully by the network without any knowledge of future ...

Online Data Gathering for Maximizing Network Lifetime in Sensor Networks
January 2007
IEEE Transactions on Mobile Computing , Volume 6 Issue 1
Publisher: IEEE Educational Activities Department
Full text available: Publisher SitePublisher Site
Additional Information:full citation, abstract, index terms
Bibliometrics:  Downloads (6 Weeks): n/a,   Downloads (12 Months): n/a,   Downloads (Overall): n/a,    Citation Count: 2

Energy-constrained sensor networks have been deployed widely for monitoring and surveillance purposes. Data gathering in such networks is often a prevalent operation. Since sensors have significant power constraints (battery life), energy efficient methods ...
