Energy consumption and network connectivity are two of the important research issues that are yet to be resolved in mobile ad hoc networks (MANETs). As taken advantage of in static networks, reliable topology control algorithms are also considered to be a good approach for mobile networks. However, a more adequate evaluation of these algorithms regarding mobility is still needed. In this paper, we...
A collection of mobile nodes in different speeds, transmission range random movement in absence of any static support of infrastructure is called a mobile adhoc network or MANET. In MANET, nodes have to announce their presence periodically and listen for their neighbors announcements broadcast to discover and learn how to reach each other. A new node is not familiar with its network topology at the...
The benefits of using mobile sink to prolong sensor network lifetime have been well recognized. However, few provably theoretical results remain are developed due to the complexity caused by time-dependent network topology. In this work, we investigate the optimum routing strategy for the static sensor network. We further propose a number of motion stratifies for the mobile sink(s) to gather real...
Mobile Ad Hoc Network is a Network composed of mobile nodes that topology is constantly changing. If in the routing in these networks, the nodes that are selected as route nodes are not stable and have a high mobility, data transmission route is broken quickly. Therefore, the method can be considered in the routing that from the nodes are between source and destination, nodes that are more stable,...
Topology control aims to provide more spatial reuse and power conservation while keeping network's connectivity. However just a few number of efforts focused on the issue of topology control with mobility. Some of topology control algorithms (e.g. CEC) try to provide more energy conservation by sleeping the redundant nodes. This paper presents a sleep-based topology control algorithm, which is in...
In autonomous ad hoc networks, nodes may act in their self-interest to improve their performance, perhaps at the expense of other nodes', or even the overall network's, performance. Besides, nodes are often mobile and must contend with limited and obsolete information about the operating state of network during their decision-making. We examine topology control of ad hoc networks and analyze the impact...
Although many medium access control (MAC) protocols have been specifically designed for WSNs where energy awareness is an essential consideration, only a few of them have considered the presence of mobile nodes or dynamic network topology in their protocols. However, they have usually considered occasional mobility, in which a few number of nodes may start moving at very low speeds and then remained...
The support of ad-hoc networks as extension of infrastructure operator networks is increasing its strength in next generation networks, due to the increasing requirement for ubiquitous access of the users. This paper describes the ad-hoc network integration mobility architecture being developed inside the IST project Daidalos II. The main purpose of this architecture is to seamlessly support the movement...
This paper proposes a new heterogeneous multi-hop cellular IP (MCIP) network that integrates multi-hop communication with cellular IP. MCIP increases the coverage of the wireless network and improves the network robustness against adverse propagation phenomena by supporting communication in dead zones and areas with poor radio coverage. MCIP includes three components: location management, connection...
