Bandwidth-constrained Clustering in Ad Hoc Networks

چکیده
We present a survey of the basic mechanisms and properties of existing clustering algorithms for wireless ad hoc networks. Based on this evaluation, we then propose a new algorithm with improved stability and a lower communication overhead. This is partly achieved by using a maintenance function that modifies the existing clustering structure rather than building a new one from scratch. Preliminary simulations seem to indicate that the algorithm produces clusters of about the same size and stability as a comparable existing algorithm, while sending significantly fewer messages.

LEBRP - A Lightweight and Energy Balancing Routing Protocol for Energy-Constrained Wireless Ad Hoc Networks
A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...

In recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...
متن کاملEfficient Clustering for Multicast Key Distribution in MANETs
Securing multicast communications in ad hoc networks must consider several challenging factors such as high nodes mobility, limited bandwidth and constrained energy. Moreover, the establishment of a key management protocol within ad hoc environments meets the “1 affects n” problem, which is more critical in such type of networks, due to the high dynamicity of groups. In this paper, we present a...
متن کاملImproving 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...
