Energy conservation is a very important design issue and has been attracting a lot of attention in recent years. The typical Mobile Ad Hoc Networks (MANET) routing protocols of the Internet Engineering Task Force (IETF) are mainly the shortest path routing protocols and do not consider the energy aware issue. This paper describes improvement of the conventional routing protocol by utilizing higher...
The trend of adopting more and more wireless mobile computers and smartphones has changed our way of living. Those devices heavily rely on the underlying wireless network systems to provide adequate communication support. As streaming audio and video becomes norm, the requests for stringent maximum end-to-end latency and minimum bandwidth make the networking process more difficult. Quality of Service...
In the area of mobile, ad-hoc networks, the quest for a GPS-free yet, location aided routing protocol is on for quite sometime. We have surveyed a number of GPS free position based routing algorithms. Specialized hardware in GPS-enabled nodes tends to increase the solution cost. On the other hand, completely GPS-free solutions typically stress on building a network-wide coordinate system. Such systems...
This paper first analyzes the mathematical model of mobile Ad Hoc networks by considering a weighted value of the ratio between sustainable energy and the total consumed energy of nodes in order to find a balance point between them. And it proposes a solution to the problem of energy efficient and load balance. Finally it presents some improvement suggestions to the AODV protocol.
This paper proposes a distributed energy-efficient routing algorithm for mobile Ad Hoc networks (MANETs). We adopt the cross-layer design paradigm. The distance from the source node to the destination node is estimated based on the received signal strength indication (RSSI) of the packets and is used to adaptively adjust the backoff time of the MAC layer. A distance threshold and a packet count threshold...
Mobile ad hoc networks have been used in the area where fixed network infrastructure is not available or wireless ad hoc connection is needed. Since mobile ad hoc network nodes are usually battery operated and it is possible that some mobile nodes will eventually run out of battery and misbehave by dropping packets to save their battery level. In this paper, we propose a routing algorithm to prolong...
Mobile ad hoc networks are a class of dynamic networks without any centralized administration. A major bottleneck in mobile ad hoc networks (MANETs) is the energy consumption since nodes are usually mobile and battery operated. To maximize the lifetime of mobile ad hoc networks (i.e., the lifetime of the nodes themselves) the power depletion of network must be evenly distributed, i.e., there must...
When nodes in a wireless mobile ad hoc network belong to different users, they may act selfishly. A feasible way to stimulate cooperation among selfish nodes is to reimburse the forwarding service providers for their costs. We propose a low overhead truthful energy-efficient routing protocol called LOTER, which introduces the VCG mechanism into such a network that consists of selfish nodes. In LOTER,...
In this paper, we investigate the issues of survivability and efficiency in a heterogeneous mobile ad hoc network (MANET) and Sensor network as a combined network where the communications is achieved using a mixed MANET and Sensor Network, referred to as SMANET for supporting mission critical applications. Using the cluster managed SMANET where, heterogeneous nodes with different capabilities and...
In the past few years there has been increasing research interest in service discovery protocols for mobile ad hoc networks (MANET). The most promising approaches so far address energy efficiency by merging the service discovery process with the routing process. Actually the service information is piggy-backed into routing messages, so that a node is simultaneously informed of available services and...
Mobile Ad-Hoc Networks (MANETS) are characterized by random, multi-hop topologies that do not have a centralized coordinating entity or a fixed infrastructure that may change rapidly over time. In addition, mobile nodes operate with portable and finite power sources. In this work, we propose an energy-efficient metric for MANETs to minimize energy consumption and increase the networkpsilas consistency...
Protecting personal privacy and energy efficiency are two primary concerns for mobile ad hoc networks. However, no energy-efficient multicast algorithm designed for preserving anonymity has been proposed to date. At the same time, existing approaches cannot be applied to anonymous routing due to their incapability of preserving anonymity. To solve this critical issue, we propose an energy-efficient...
