Congestion control using distributed link scheduling in wireless networks

Abstract

In a wireless multi-hop system the communication between the two endpoints is carried out by a some intermediate nodes whose function is to relay information from one point to another. Although there has been exploitation of the physical layer technique enhance the capability of multi-trip system, link scheduling problems still exist. Link scheduling problem addressed with a cross layer design. Cross layer design is a process of solving congestion and scheduling problems in wireless systems wherever nodes capable by way of the Successive interference cancelation (SIC) capability under Signal to Interference Noise Ratio (SINR) model. SIC an efficient advance to tolerate the multiple adjacent concurrent communication to coexist, enable multi-packet reception. Cross layer design placed among the physical layer and MAC layer. The technique of both layers can support the additional difficult cross layer design intended use of improve system process. The proposed system consists of distributed link scheduling for solving the interference occurring during communications. This scheduling is an effectual process used for managing the interference relationships and with the help of advanced physical layer technique using SIC to take out the interference moreover decode the data by receivers.
