Wireless Sensor Networks (WSNs), having inherent features, require new protocols and algorithms for QoS provisioning in realtime multimedia applications. In this paper, we present a new cross-layer communication module, called XLCM and its protocol XLCP enabling scalable service differentiation in WSNs. We implemented XLCP as a module in NS-2 simulator to evaluate its performance. The results indicate...
Recently, popularity of multimedia content sharing among the Internet users and development of wireless mobile devices have promoted a trend of deploying Peer-to-Peer (P2P) networks over mobile ad hoc networks (MANETs) for mobile content distribution. However, due to nodes' frequent movement, limited radio transmission range, sparse distribution and power limitations, MANETs may become Delay Tolerant...
IEEE 802.11e is the indisputable standard for supporting multimedia traffic in modern Wireless Local Area Networks. However, it has been proven incapable of handling efficiently multimedia flows in congested networks. The main reason for this suboptimal behavior roots from the static nature of resource allocation specified in IEEE 802.11e. Dynamic tuning of the MAC parameters has demonstrated a beneficial...
