Wireless mesh networks have recently gained a lot of popularity due to their rapid deployment and instant communication capabilities. Special routing protocols are employed, which facilitate routing between the Mesh Routers as well as between the Mesh Routers and the Mobile Nodes. This work addresses a framework of packet routing in the wireless mesh network. We investigate a cross-layer solution...
The IEEE 802.11 Task Group E is working on a QoS-aware MAC protocol involving Enhanced Distributed Channel Access (EDCA). This scheme was developed to offer QoS capabilities to WLAN, offering significant improvements to multimedia traffic. MANETs will also benefit from this new technology since the most widely deployed and used wireless cards are those based on IEEE 802.11. The use of transmission...
Obviously, the energy is one of the important metrics to consider when designing communication protocols for mobile ad hoc networks (MANETs). In this paper, we demonstrate the importance of considering energy saving in MANETs. Our analysis are based on the comparison of two energy-based mechanisms called E-AODV, an energy consumption rate-based routing protocol, and F-AODV, a cross-layer-based routing...
The cross-layer design approach is an important concept in mobile ad-hoc networks which is adopted to solve several open issues. It aims to overcome MANET performance problems by allowing protocols belonging to different layers to cooperate and share network status information while still maintaining separated layers. While cross-layer model could enhance the performance of the applications and achieve...
In this work, we present a cross-layer forwarding strategy (CLFS), which is based on the cooperation between the new IEEE 802.11e MAC protocol (EDCA) and the on-demand AODV routing protocol. The proposal aims to minimize the number of forwarding nodes (FN) by hop, in the network. By this way, we decrease the contention amount and we improve the medium utilization. The selection of FN is based on maximum...
Nowadays, the cross-layer design approach is an important concept in mobile ad-hoc networks which is adopted to solve several open issues. It aims to overcome MANET performance problems by allowing protocols belonging to different layers to cooperate and share network status information while still maintaining separated layers. Indeed, the mechanisms on how to access the radio channel are extremely...
