چکیده
Abstract: In this paper we study the outage probability that is the complement of transmission success probability to be the probability of the SINR received by a typical receiver is more than a specified threshold in wireless ad hoc networks. Even though calculating the exact outage probability is usually impossible but considering special distributions for node distributions in wireless networks and using the Laplace transform we calculate upper bounds on the outage probability that is very important in networking because from that and putting an outage constraint on outage probability we can easily drive the maximum density of successful transmissions and this shows how wireless networks are affected by outage probability. To model the outage probability we consider a large wireless ad hoc networks that its node are distributed in plan according to a point process and assume that our interference to be a product of path-loss attenuation and a fading coefficient then compute the derived results for special rvs. Using the results for outage probability we can have bounds on TC that recently is known as the most important factor in the study of wireless ad hoc networks.

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes.
