In this paper, we propose IAMAC, an interference avoidance MAC protocol to avoid inter-node interference in dense wireless sensor networks. IAMAC interacts with routing protocol via cross-layer information sharing between the MAC and network layer. By providing information from network layer, we enable the MAC protocol to make proper decisions which result in fewer inter-node interference and lower...
Mobile ad hoc network (MANET) consists of a collection of wireless mobile hosts without the required intervention of any existing infrastructure or centralized access point such as base station. The dynamic topology of MANET allows nodes to join and leave the network at any point of time. Wireless MANET is particularly vulnerable due to its fundamental characteristics such as open medium, dynamic...
A mobile ad hoc network (MANET) is a wireless network that does not rely on any fixed infrastructure (i. e., routing facilities, such as wired networks and access points), and whose nodes must coordinate among themselves to determine connectivity and routing. The broadcast can target a portion of the network (e. g. gathering neighborhood information), or the entire network (e. g., discovering routes...
This paper presents a location based store-and-forward packet routing algorithm for wireless body area networks (WBAN) with frequent postural partitioning. A prototype WBAN has been constructed for experimentally characterizing on-body topology disconnections in the presence of ultra short range radio links, unpredictable RF attenuation, and human postural mobility. A location based packet routing...
Multicast services are used in emerging multimedia applications based on Quality of Service (QoS) development of multimedia group application and the construction of multicast routing tree is significant. Upper bound on the delay between sender and receiver is one of the common QoS constraints. Delay-constrained routing protocols are used to find paths subject to the delay constraint while efficiently...
Link state routing mechanisms have shown good convergence behaviour in networks with mobile hosts. Compared to traditional link state mechanisms, which suffer from broadcast storm problems in mobile ad hoc networks (MANETs), pruned link state approaches such as those used in optimized link state routing (OLSR) have shown significant reduction in the control overhead. In this paper, we show that the...
