....in x 4. Finally, in x 5 the survey concludes by revisiting the open problems of the field of dependable ad hoc networks and by suggesting new directions. 2 Mobility Models Researchers have proposed many mobility prediction schemes to predict the future availability of wireless links [11] [12], 13] These models have been used (1) to describe how mobile hosts move so as to evaluate the performance of the proposed routing protocols in a realistic representation of the scenario in which the protocol would be actually used, and (2) to predict the network connectivity during a routing ....

....an end host. Node mobility leads to frequent disconnections of wireless links, hence the network topology changes dynamically. Network layer routing is an extensively researched area of ad hoc networks. To improve network connectivity, researchers have proposed many mobility prediction schemes [1] [2] [3] to predict the future availability of wireless links, for the purpose of building more stable end to end connections. In contrast, there are fewer studies of the effect of dynamic network topology on application level issues, such as the provisioning of centralized service in wireless ad hoc ....

....the time when the received signal strength falls below a critical threshold using a measured value of average change in received signal strength. Another prediction method for link durations is presented in [6] The method is based on distance measurements between mobile devices. A refinement in [7] takes possible changes in speed or direction of motions into account. The distance between connection peers may be acquired with the help of GPS receivers or signal strength measurements. Apart from the shortcomings of these two methods, the problem with this approach is that the distance of a ....

....can predict for an active link with another node by measuring relative distances between them without knowing the velocities of their movements. Su and Gerla [95] proposed a similar scheme where the velocity of a nodes movement is supposed to be known by using Global Position Systems (GPS) In [44], link availability can be estimated by prediction and routing metrics. Although the prediction algorithms cannot accurately calculate the link availability, it can reflect the general tendency of a link availability as shown by the simulation results presented in [44] Bandwidth estimation ....

Although the prediction algorithms cannot accurately calculate the link availability, it can reflect the general tendency of a link availability as shown by the simulation results presented in [44]. Bandwidth estimation Estimating available network capacity at real time is a difficult problem, since the effective latency and bandwidth between a mobile host and other nodes is constantly changing. 2.3.

....reliability model that derives end to end reliability between the source and destination nodes by evaluating the path reliabilities of all existing feasible paths. The path reliability is calculated based on the link availabilities of all the links along a path. According to Jiang et al. [3] and McDonald et al. 6, 7] link availability is defined as the probability that a link is available until time , given that it is an active link at time . The calculation of link availability is based on the current node s movement [3] A path is defined as a sequence of links from ....

According to Jiang et al. 3] and McDonald et al. 6, 7] link availability is defined as the probability that a link is available until time , given that it is an active link at time . The calculation of link availability is based on the current node s movement [3]. A path is defined as a sequence of links from the source node to the destination node. Path reliability is the product of link availabilities of all the links along the path under the assumption that all links are independent. If we denote the link availability of the link connecting node and ....
