Since wireless sensor nodes are battery powered, the emphasis was on reducing the energy consumption of the sensor nodes. However, with the increase in real-time traffic requirements in wireless sensor nodes, network performance metrics are increasingly important. Nonetheless, most existing network performance studies were done via simulation, with few experimental studies performed on testbeds using...
New generation of mobile wireless networks utilizes IP mobility protocols to handle handovers between their different subnets. Among existing options, Proxy Mobile IPv6 (PMIPv6) as a network-based protocol presents higher handover performance comparing with its client-based counterparts such as Mobile IPv6 (MIPv6) and Hierarchical Mobile IPv6 (HMIPv6). Nevertheless, the PMIPv6's operation is limited...
In order to fulfil the demand for on-the-move and uninterrupted internet connectivity in Mobile Networks, the IETF (Internet Engineering Task Force) has standardized NEMO Basic Support Protocol in as RFC 3963. However, providing a low latency handoff performance in mobile networks by using fast handover mechanism to ensure a seamless mobility for users is one of the main objectives of ongoing research...
Wireless ad hoc networks are a collection of mobile nodes spreading over a defined geographical area, enabling realtime collaborative applications such as push-to-talk and VoIP. Unfortunately, wireless ad hoc networks suffer from limited bandwidth and QoS constraints. A proposed eXplicit MultiCAST (XCAST) based routing protocol (P-XCAST) is presented in this paper to support team-based communications...
In most of the ad-hoc routing protocols, a static link lifetime (LL) is used for a newly discovered neighbors. Though this works well for networks with fixed infrastructures, it is inadequate for ad-hoc networks due to nodes mobility and frequent breaks of links. To overcome this problem, routing protocols with estimated LL using nodes affinity were introduced. However, these protocols also used the...
