“…However, such a statement can be too strong in many scenarios, particularly when we are interested in actual protocol design rather than carrying out an asymptotic analysis. As explained as follows, the results in [3] and [5] do not really prove that the cross-layer design is not necessary.…”

“…Based on the result of order-optimal multihopping, it is stated in [3] that the decode-and-forward strategy can achieve optimal performance, within a constant, with regard to the network capacity. It is also pointed out in [3] that a natural way of implementing the decode-and-forward strategy is the layered-protocol architecture. Consequently, it is concluded that the cross-layer design can only improve throughput by at most a constant factor and that an unbounded performance improvement cannot be achieved.…”

“…However, critical issues must be considered for cross-layer design [3], because it has risks due to loss of protocol-layer abstraction, incompatibility with existing protocols, unforeseen impact on the future design of the network, and difficulty in maintenance and management. Thus, certain guidelines need to be followed when carrying our cross-layer design.…”

Abstract-The conventional layered-protocol architecture does not provide optimal performance for wireless mesh networks (WMNs). The method of optimization decomposition of the protocol stack can achieve optimal network performance. This method usually results in a clean-slate protocol architecture that is different from the protocol architecture of WMNs. Such a difference actually demonstrates the need for a cross-layer design. Specific features pertaining to WMNs also show the need for cross-layer optimization across different protocol layers. In this paper, motivations for cross-layer design in WMNs are stated first. Moreover, cross-layer optimization schemes and algorithms between different protocol layers are investigated with an objective of shedding light on open research problems and new approaches. Guidelines for carrying out cross-layer design in WMNs are also provided in this paper.

“…Cross layer interaction was proposed in the literature as a solution to avoid bottlenecks of the strict layered protocol design in wireless networks. On the other hand there are some controversial arguments about cross layer interactions in wireless networks [4]. Kawadia and Kumar [4] argue that once the layers are broken through cross layer interactions, it affects not only to the layer concerned but also to the other parts of the system.…”

Real time mobile communication is challenging due to the inherent limitations of mobile networks. On the other hand the stringent quality of service requirements of real time traffic is highly in demand. Our first contribution is the generic context aware architecture for adaptive real time applications. Adaptation is based on the awareness of context parameters from different layers of the existing protocol stack which involves context exchange among the neighboring layers as well as non-neighboring layers. The architecture comprises of context representation, context acquisition, cross-layer context exchange and context management. Our second contribution is the mobility aware, adaptive Multi-homed Mobile IP. Simulation of adaptive M-MIP was carried out as a proof of concept. Simulation demonstrated that adaptation to mobility was able to decrease Mobile IP handover latency. Further, the results show that the quality of service of real time traffic can be enhanced by using context aware adaptive MIP. The simulation involved with various speeds ranging from pedestrian scenarios to vehicular scenarios. Results are analyzed with variable data rates. The evaluations show that performance of the proposed solution is better compared to conventional MIP in terms of packet loss and throughput of real time traffic.
