Abstract:

The distance-aware adaptive relay selection and quality of service (QoS) support algorithm are proposed based on performance of wireless communication. The adaptive cooperative error control mechanism based on cross-layer of hybrid automatic repeat request and automatic repeat request (HARQ-ARQ) is provided. A Markov chain model is built for analyzing the performance of wireless communication according to three different states of the data packets. In the mechanism, ARQ is used at the physical layer and hybrid ARQ is used at the data link layer. Cooperative transmission over multiple relays is proposed based on adaptive relay selection according to the performance between the sending sensor and receiving sensor. Analyses and simulation show that, compared to the traditional ARQ, traditional HARQ, cooperative ARQ and hybrid ARQ respectively, the proposed mechanism could have a better performance in terms of saturation throughput rate, reliability and energy efficiency.

Key words: wireless sensor networks, cooperative communication, cross-layer design, distance aware, automatic repeat request, quality of service supported
