| Abstract: | The delay performance of mobile Ad hoc networks with two-hop relay algorithm is analyzed. Computing the mean transition steps of the geometric random process and joint probability distribution of random variables, the closed-form expression of the delivery delay upper bound and the optimal transmission redundancy strategy are obtained. Further, based on mean residual service time, the end-to-end delay performance is derived. Finally, the numerical results show the relationship of delay performance with the network size and the traffic load. |
