Impact of Intra-Flow Interference on the Performance of 2-D Multi-Hop Cooperative Network

A mathematical model is proposed to study the effects of intra-flow interference caused due to multi-packet propagation in a 2-D cooperative opportunistic large array network. Specifically, the outage probability of node is derived in the presence of interfering signals using the ratio distribution of generalized integer gamma random variables. The outage probability expression is used along with a Markov chain-based transmission model to quantify the state distribution probabilities, coverage of the network, and network throughput. The results show that the network performance is highly dependent on intra-flow interference especially at high signal-to-noise ratio. Moreover, the coverage of network can be improved by increasing SNR, array gain, and packet insertion rate.
