Exploring long lifetime routing (LLR) in ad hoc networks

Zhao Cheng, Wendi B. Heinzelman
2004 Proceedings of the 7th ACM international symposium on Modeling, analysis and simulation of wireless and mobile systems - MSWiM '04  
In mobile ad hoc networks, node mobility causes links between nodes to break frequently, thus terminating the lifetime of the routes containing those links.  ...  In this paper, we first formulate the distribution of a link lifetime and correspondingly the distribution of a route lifetime.  ...  INTRODUCTION In an ad hoc network, there is no pre-existing fixed network architecture.  ...

Routing protocols in ad hoc networks: A survey

Azzedine Boukerche, Begumhan Turgut, Nevin Aydin, Mohammad Z. Ahmad, Ladislau Bölöni, Damla Turgut
2011 Computer Networks  
In addition, in some applications, ad hoc networking is really the only feasible solution, while in other applications, ad hoc networking competes with other technologies.  ...  Thus, the performance expectations of the ad hoc networks differ from application to application and the architecture of the ad hoc network, thus each application area and ad hoc network type must be evaluated  ...  Long Lifetime Route (LLR) [28] : Cheng and Heinzelman argue that many routes in ad hoc networks are short lived, triggering frequent route discovery processes, which in turn account for extra control  ...

EXIT-Chart-Aided Hybrid Multiuser Detector for Multicarrier Interleave-Division Multiple Access

Rong Zhang, Lei Xu, Sheng Chen, L. Hanzo
2010 IEEE Transactions on Vehicular Technology  
A generically applicable hybrid multiuser detector (MUD) concept is proposed by appropriately activating different MUDs in consecutive turbo iterations based on the mutual information (MI) gain.  ...  It is demonstrated that the proposed hybrid MUD is capable of approaching the optimal Bayesian MUD's performance despite its reduced complexity, which is at a modestly increased complexity in comparison  ...  ACKNOWLEDGMENT Index Terms-Lifetime prediction, link lifetime (LLT), mobile ad hoc networks (MANETs), node lifetime, route discovery, routing protocol.

Investigation of mechanisms for routing in mobile ad-hoc network

H Bakht
2017
This chapter explored the relation between the routing mechanisms for fixed and mobile ad-hoc networks.  ...  Routing in ad-hoc sensor and ad-hoc networks suffers with some of the similar constraints.  ...  However, MAODDP outclassed AODV in terms of generating ACK messages. These ACK messages in MAODDP serve two purposes i. e. establishment of route and simultaneous data delivery.  ...

Stability and hop-count based approach for route computation in MANET

K.N. Sridhar, Mun Choon Chan
Proceedings. 14th International Conference on Computer Communications and Networks, 2005. ICCCN 2005.  
In this paper, we present an approach for MANET routing based on stability and hop-count, where the stability metric considered is the residual lifetime of a link.  ...  SHARC also performs close to an algorithm with perfect knowledge of link residual lifetime in many cases.  ...  [4] studies the issue of link duration in mobile wireless ad hoc network and is closest to our work.  ...
