Physical and MAC Cross-Layer Analysis of Energy-Efficient Cooperative MIMO Networks

CL-mWSNs: Cross Layer Model-Based QoS Centric Routing Protocol for Mission-Critical Cooperative Communication in Mobile WSNs

“…The majority of the existing approaches rely on single parameter-based routing decision-making schemes, where the emphasis is placed on augmenting PHY and MAC [3], [4], [9], [12], SD functions [9], congestion avoidance at MAC [19] etc. However, very few efforts have been made to make the routing decision while considering the type of data and its priority, to ensure deadline sensitive communication [12].…”

“…On the contrary, it is a fact that inclusion of these all factors, network condition-aware routing with synchronized cross-layer information may improve BFN selection and routing decisions. With this motivation, in this research a reference model has been developed that combines the major efficacies of multiple contributions made, such as in [3], [4], [9], [12], [19], [22]. Although in [3], the authors considered only the MAC and PHY layers where throughput and link-outage probability (at MAC) were used to perform PHY switching control, they could not address other aspects, such as packet transmission rate or packet velocity of a node, which is a must for deadline-sensitive, mission-critical communication.…”

In addition, they applied a classic prioritization scheme, which offered less or even no concern to fair resource scheduling for NRT data.…”

“…This model could not offer the provision of better SD. Noticeably, the aforementioned routing cross-layer models [3], [4], [9], [12], [19] have implemented a cross-layer model, but for static WSNs only. They have not addressed the exceedingly dynamic topology of a mobile WSN.…”
