摘要

提出了服务区分动态退避算法——SDDB算法

通过对优先级不同的业务采用不同的退避方式

能在不显著降低网络吞吐量的同时

实现合理退避及业务优先级区分服务

有效避免二次冲突

支持突发业务流传输

保障优先级高的业务的实时传输要求

更适合多种业务并存的无线多媒体传感器网络。

Abstract

A new SDDB backoff algorithm in MAC layer for wireless multimedia sensor networks was proposed

which could use different backoff scheme to different priority flows.It can support different services and avoid second-collision effectively.SDDB is able to ensure the demand of real-time traffic transmission

which doesn’t reduce the throughput.Simulation results show that SDDB algorithm is more suitable for WMSN.
