Wireless communication is increasing along with improvements in chipset performance. New applications associated with the Internet of Things (IoT) often involve self-organization and collaboration among many autonomous wireless devices for which traditional infrastructure-based wireless networks are not suitable. Mobile Ad hoc Networks (MANETs), with their infrastructure-less, spontaneous and arbitrary multi-hop features are considered a popular approach for such scenarios, although they also face certain inherent challenges. These include: the limited communication range of each mobile node, power supply restrictions and frequent link breaks due to node movements. In this paper, in order to address the lack of a systematic cooperative routing scheme, we propose a novel protocol called Cooperative Relay Routing Protocol (CRRP) for data transmission in MANETs. Since node mobility can cause frequent radio link breaks, one of CRRP's pivotal design features is to enhance resilience, therefore improving the overall network throughput. This is achieved by forming localised cooperative (COP) topologies where appropriate. Furthermore, as nodes are often battery-powered, CRRP reduces the energy consumption when packets are forwarded by exploiting cooperative diversity. We assess the performance of CRRP via simulations and the results confirm its favorable operation compared to both classic and newer energy-aware MANET routing protocols.
