An adaptive opportunistic retransmission control scheme environment-aware-based for wireless multimedia Mesh networks

Abstract

In this paper, we propose an aware-based adaptive opportunistic retransmission control scheme for wireless multimedia Mesh networks. The proposed scheme provides maximum retransmission count optimization based on environment-aware to improve packet relay probability. The scheme discriminates the types of packet loss in wireless link by means of environment information and selects the retransmission count by taking the IEEE 802.11 wireless channel characteristics into consideration. Furthermore, the maximum retransmission count of MAC is adjusted adaptively. Extensive simulations demonstrate that the proposed scheme significantly reduces packet collision probability and packet loss rate, and thus improves network throughput.

A Flexible and Reliable Traffic Control Protocol for Wireless Multimedia Sensor Networks

“…Reference [13] proposes NACK-based repair mechanism coupled with an adaptive MAC layer retransmission scheme in order to reduce real-time end-to-end delay while maintaining reliability and energy efficiency in the presence of high channel error rates. Reference [14] proposes an aware-based adaptive opportunistic retransmission control scheme for WMSNs. The maximum number of retransmissions is adjusted adaptively.…”
