“…The basic objective of the selection of relay nodes is done by using traditional algorithms by considering either link quality or receiver signal strength. Multihop routing provides an optimal utilisation of resources and increases throughput (Kim et al, 2009;Boukerche et al, 2011;Lin et al, 2008;Kim et al, 2012). In wireless medium identified routes uses various links to forward the packet.…”

WiMedia plays a major role in the domain of personal area networks owing to its ability to support high data rate. It is used for constructing home networks, establishing virtual multimedia connectivity for video or audio sharing and so on. Maximising the utilisation of the available resources in an efficient manner is one of the objectives in wireless networks. In order to provide better resource utilisation, parameters such as resource allocation, provisioning and monitoring need to be considered. In extremely occupied situations, mobility, interference and link quality may also be addressed. Poor link quality results in slow and unreliable network connection. Therefore, resource provisioning with good signal strength is a challenging task. By considering the mobility and link quality factors along with relaying concept, a simple distributed cooperative relay-based routing protocol is designed to reduce the resource starvation and enhance the utilisation for WiMedia. Unlike conventional routing algorithms, the proposed approach minimises the delay, which in turn maximises the throughput by choosing a better link quality.

“…In [14], the authors have proposed two MAC protocols (Repetition coding with maximal ratio combining MAC (MRC -MAC), Space time coding MAC(STC MAC)) and two routing protocols (Cooperative Routing Protocol (CRP), Enhaced CRP (E-CRP)). MRC-MAC is the MAC protocol to support repetition coding with MRC at the physical layer.…”

Cooperative communication refers to the collaborative processing and retransmission of the overheard information at those stations surrounding the source. It exhibits various forms at different protocol layers and introduces many opportunities for cross layer design and optimization. To fully reap the benefits of cooperative communications in wireless networks, the entire protocol stack -physical, MAC, and routing protocols -should be carefully redesigned or reengineered. In this paper, we first propose a cooperative MAC protocol by enhancing IEEE 802.11 DCF with minimal modifications to maximize the benefit of cooperative diversity. Its performance is compared to that of an existing cooperative MAC and legacy 802.11 DCF protocols and shown to be superior. We also propose a cluster based cooperative routing protocol which has minimal control overhead and time consumed in establishing the cooperative paths. Through extensive simulations, the performance of the proposed protocols are evaluated and compared to other combinations of MAC and routing protocols.

“…In , the selection of relaying candidates are implemented by using Hello messages. By exchanging the Hello messages, a set of nodes, which are the common immediate neighboring nodes for both of the source and destination, are selected as the relaying candidates.…”

“…In , for a link between the source s and the destination d, the source considers the immediate neighboring nodes of both s and d as relaying candidates. The source maintains a list that contains the candidates' MAC addresses and their link qualities to s and d. The source uses a metric γ r , as shown in Equation ,

γ_{normalr} = min (S N R ((), {s,r}_{i}), S N R (() {normalr}_{i}, d))

to sort the candidates, where SNR (s,r i ) and SNR (r i , d) denote the SNR between the link of s– r i and r i – d, respectively.…”

Relay selection schemes for cooperative communications to achieve full cooperative diversity gains while maintaining spectral and energy efficiency have been extensively studied in a recent research. These schemes select only the best relay from multiple relaying candidates to cooperate with a communication link. In the present paper, we reviewed recently proposed cooperative communication protocols that integrate with relay selection mechanisms. The key design issues for relay selection mechanisms, for example, relaying candidate selection, optimal relay assignment, and cooperative transmission, were identified. We further discussed the challenges of optimal relay assignment in multi‐hop wireless sensor networks and presented the potential applications of cooperative communications with a relay selection in such networks. Future research directions were outlined, for example, the issues of service differentiation and system fairness in cooperative communication systems and the joint use of game theory and adaptive learning techniques in relaying candidate selection and optimal‐relay assignment mechanisms for efficient allocation of network resources.
