Span: An Energy Efficient Coordination Algorithm for Topology Maintenance in Ad Hoc Wireless Network
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 8
Abstract
This paper presents Span, a power saving technique for multi-hop ad hoc wireless networks that reduces energy consumption without significantly diminishing the capacity or connectivity of the network. Span build son the observation that when a region of a shared channel wireless network has a sufficient density of nodes, only a small number of them need be on at any time to forward traffic for active connections. Span is a distributed, randomized algorithm where nodes make local decisions on whether to sleep, or to join a forwarding backboneasacoordinator.Wegiverandomizedalgorithmwherecoordinatorsrotatewithtime, demonstrating how localized node decisions lead to a connected, capacity-preserving global topology. Improvement insystemlifetimedue to Span increases as the ratio of idle-to-sleep energy consumption increases. Our simulations show that with a practical energy model, system lifetime of an 802.11network in power saving mode with Span is a factor of two better than without. Additionally, Span also improves communication latency and capacity.
