Ad Hoc Wireless Multicast With Mobility Prediction

An ad hoc wireless network is an infrastructureless network composed of mobile hosts. The primary concerns in ad hoc networks are bandwidth limitations and unpredictable topology changes. Thus, efficient utilization of routing packets and immediate recovery of route breaks are critical in routing and multicasting protocols. A multicast scheme, On-Demand...

Reliable Multicast in Wireless Sensor Networks

Multicasting in Wireless Sensor Networks WSNs is an efficient way to disseminate the same data to multiple receivers. For critical tasks such as code updates, reliability would be a desirable feature, in order to use multicasting for such scenarios. Due to the nature of WSNs, several problems exist that make...

On Multicasting in Wavelength-Routing Mesh Networks

This paper considers multicasting on wavelength-routing mesh optical networks. Although multicasting has been studied extensively in different network environments, multicasting in this environment is different, and more involved. The paper discusses the challenges of multicast support in optical wavelength routing networks, and reports on the advances made so far in...

Adaptive Two-Tier Energy-Efficient Multicasting in Mobile and Wireless Ad Hoc Networks

This paper studies the problem of energy-efficient multicasting in mobile and wireless ad hoc networks. To deal with node mobility, the paper presents a two-tier multicasting model which consists of mobile nodes and stationary nodes. Mobile nodes achieve multicasting through the closest stationary node at lower tier. Stationary nodes route...

Scalable Multicasting in Mobile Ad Hoc Networks

Many potential applications of Mobile Ad hoc Networks MANETs involve group communications among the nodes. Multicasting is an useful operation that facilitates group communications. Efficient and scalable multicast routing in MANETs is a difficult issue. In addition to the conventional multicast routing algorithms, recent protocols have adopted the following new...

A Caching Mechanism to Improve the Reliability of Multicasting in Multihop MANET

Reliable multicasting takes help of re-transmissions from the source, to recover lost packets .This imposes a huge overhead on the bandwidth-constrained ad hoc network. In On Demand Multicast Routing Protocol ODMRP, the multicast members send Join Replies to the periodic Join Queries initiated by the source, to maintain their membership....
