Wireless ad-hoc networking will be a fundamental component of emerging technologies such as multi-hop cellular networks, vehicular ad-hoc networks and wireless mesh networks, with most of these technologies based on evolved versions of the 802.11 standard. To achieve their expected benefits, and address their challenges, in terms of energy efficiency, reliability or reconfigurability, advanced cooperative...
In this paper an innovative framework based on the cooperation between MAC and routing protocols is proposed with the purpose of improving the reliability of multicast transmissions in a Mobile Ad hoc NETwork (MANET). The proposed framework adds new features to the On-Demand Multicast Routing Protocol (ODMRP) and to the IEEE 802.11MAC layer. This choice allows to exploit the mesh-based nature of the...
Broadcast/multicast is a service of paramount importance for wireless users, which poses several serious challenges. Many multicast applications, such as multicasting streaming or alarm signalling, require a reliable and efficient medium access control (MAC) layer. However, the current IEEE 802.11 protocol does not offer any MAC layer recovery mechanisms on unsuccessfully delivered broadcast/multicast...
Many multipath routing schemes have recently been proposed to improve the performance of wireless networks. Multipath routing is supposed to reduce the end-to-end packet delay and increase the packet delivery ratio. Therefore, it can also improve the packet delivery ratio in vehicular ad hoc networks (VANETs) when the mobility of relaying vehicles is unknown. However, in wireless networks, multiple...
