Paper Abstract:
|
A Mobile Ad Hoc Network (MANET) is a network consisting of a set of mobile hosts. Energy efficiency is a critical
issue in MANETs since mobile hosts are with limited energy. Geographical Adaptive Fidelity (GAF) protocol proposed
the grid-based architecture based on the idea of connected dominating set. It divides the whole network area into disjoint
identical square grids, called virtual grids. In each grid, there is only one node for forwarding packets to achieve power
saving. In this paper, we propose the Hierarchical Energy Conservation protocol (HEC). In this protocol, in order to
increase the coverage of wireless transmission, it divides the whole network area into disjoint hexagonal grids instead of
square grids and employs the hierarchical group control mechanism. Mathematical analysis and simulation results show
that the proposed protocol not only prolongs the lifetime of MANETs but also maintains appropriate packet delivery ratio
and latency. |
