- Abstract
Underwater acoustic sensor networks have unique characters challenging the protocol design. In this paper, the fundamental issues of underwater acoustic sensor network, i.e., reliability and energy efficiency, are investigated. A set of lightweighted distributed location based routing protocols, Modified Hop-by-Hop Vector-Based Forwarding (MHFI-VBF), are proposed. The cross layer design is effectively implemented by the time series states estimation algorithms, Weighted Moving Average (WMA) and Exponential Smoothing (ES). Even under very harsh conditions, Ml II l-VBFs can still maintain fairly well success rate and low energy cost with only local information exchanges. The cross layer protocol stack optimized by time series states estimation models defeat original VBF based protocols with predominant advantages. The evaluation results verify that MHH-VBFs have more advantages on overall performance.
