Abstract
Conference Title: 2018 IEEE 88th Vehicular Technology Conference (VTC-Fall) Conference Start Date: 2018, Aug. 27 Conference End Date: 2018, Aug. 30 Conference Location: Chicago, IL, USA This paper studies the performance of a cooperative opportunistic large array (OLA) network, in which the nodes are deployed randomly in a strip-shaped fashion. Specifically, the source and the destination nodes are separated by a large distance and a number of randomly deployed relay nodes help the source message to be delivered to the destination using multi-hop cooperation strategy. The performance of network is carried out in terms of the success rate and the average number of hops to reach the destination. The reliability of the OLA network is increased, when the same message is transmitted by a group of nodes in multiple hops by exploiting spatial diversity gains. Towards the end, energy efficiency in the networks can be achieved by limiting few nodes in each hop without compromising on the quality of service (QOS). The paper summarizes and compares the performance of various network topologies in terms of energy efficiency and outage probability.
