Impact of the Dynamic Membership in the Connectivity Graph of the Wireless Ad hoc Networks
Mobility Metrics of the connectivity graphs with fixed number of nodes have been presented in several research studies over the last three years. More realistic mobility models that are derived from real user traces challenge the assumption of the connectivity graph with fixed number of nodes, but they rather show that wireless nodes posses dynamic membership (nodes join and leave the simulatio...

A new method to quantify, monitore and assess ecological structures and functions is the application of graph theory. In ecology, this theory demonstrates its suitable application in assessment of ecological connectivity. Connectivity is the structural attribute of landscape which facilitates the species movement among their habitats. Using graph theory, this paper aims to assess the connectivi...
متن کاملA framework for evaluating DTN mobility models
The field of delay tolerant networking is rich with protocols that exploit node mobility to overcome unpredictable or otherwise bad connectivity. The performance of many of these protocols is highly sensitive to the underlying mobility model which determines the nodes’ movements, and the characteristics of these mobility models are not often studied or compared. With few exceptions, authors tes...
متن کاملClassification and Evaluation of Mobility Metrics for Mobility Model Movement Patterns in Mobile Ad-Hoc Networks
A mobile ad hoc network is collection of self configuring and adaption of wireless link between communicating devices (mobile devices) to form an arbitrary topology and multihop wireless connectivity without the use of existing infrastructure. It requires efficient dynamic routing protocol to determine the routes subsequent to a set of rules that enables two or more devices to communicate with ...
متن کاملMobility Metrics Evaluation for Self-Adaptive Protocols
Cross-layer mechanism, for which a protocol locating at a given layer uses information issued from other layers, may enhance the mobile networks performance. Some of those mechanisms are based on mobility metrics. For example, the establishment of a route by choosing less mobile nodes could improve the routing protocol. In this paper, we study the ability of mobility metrics to reflect the mobi...
