Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
متن کاملExploiting Routing Redundancy Using a Wide-area Overlay
As new and interesting peer-to-peer applications combine with advancements in networking technology, they are reaching millions of users across the globe. Numerous studies have shown, however, that loss of connectivity is common on the wide-area network, due to hardware and software failures, and network misconfigurations. Despite the natural redundancy present in underlying network links, the ...
متن کاملA Reliable Routing Algorithm for Delay Sensitive Data in Body Area Networks
Wireless body Area networks (WBANs) include a number of sensor nodes placed inside or on the human body to improve patient health and quality of life. Ensuring the transfer and receipt of data in sensitive data is a very important issue. Routing algorithms should support a variety of service quality such as reliability and delay in sending and receiving data. Loss of information or excessive da...
متن کاملEfficient Source Authentication for Multicasting in MANETs
1 Abstract— In this paper, we investigate a popular source authentication scheme, TESLA (Timed Efficient Stream Loss-tolerant Authentication) for multicast communication in mobile ad hoc networks. We evaluate the performance of a source authentication scheme inspired from TESLA and TESLA based on simulations. Time synchronization is a crucial assumption made by these schemes. We describe effect...
متن کاملRouting in Overlay Multicast Networks
Multicast services can be provided either as a basic network service or as an application-layer service. Higher level multicast implementations often provide more sophisticated features, and can provide multicast services, where no network layer support is available. Overlay multicast networks offer an intermediate option, potentially combining the flexibility and advanced features of applicati...
