Executive Summary

This paper describes a frame work investigating the performance of Distributed Spatial Multiplexing (DSM) in cooperative multi-hop cellular networks. The cooperative communication in cellular networks gives them leverage to get the inherent advantages of its random relay locations and the direction of the data flow. However, traditional centralized relay selection needs considerable overhead and signaling. In the authors proposed work, threshold based relay selection is adopted based on the Received Signal Strength (RSS) and Signal to Noise Ratio (SNR). The best relay chosen will transmit jointly with source using Amplify and Forward (AF) protocol. The evaluation is performed with Bit Error Rate (BER) and energy per bit for distributed spatial multiplexing scheme with multi-hop networking.
