In wireless ad-hoc networks, wireless mobile hosts communicate with each other, in the absence of a fixed infrastructure. In these days, as the energy issue becomes more important. Here it is known that data transmissions are one of the main factors of the power consumption of mobile hosts. Therefore, energy efficient data access is one of the most important research issues for data sharing applications in Ad-hoc networks.
In the paper, improve LAR (Location-Aided Routing) which is one of the most famous location based routi ....etc

ABSTRACT

Due to the emergence of multimedia context-rich applications and services over wireless networks, networking protocols and services are becoming more and more integrated, thus relying on context and application information to support their operation. Further, wireless protocols and services now employ information from several network layers and the environment, breaking the layering paradigm. In order to cope with this increasing reliance on information, we have proposed MANIP, a middleware for MANETs that instantiates a new networ ....etc

Abstract—The multihop routing in wireless sensor networks (WSNs) offers little protection against identity deception through replaying routing information. An adversary can exploit this defect to launch various harmful or even devastating attacks against the routing protocols, including sinkhole attacks, wormhole attacks, and Sybil attacks. The situation is further aggravated by mobile and harsh network conditions. Traditional cryptographic techniques or efforts at developing trust-aware routing protocols do not effectively address this sever ....etc

Abstract.
In context-aware systems, there is a high demand on providingprivacy solutions to users when they are interacting and exchanging personalinformation. Privacy in this context encompasses reasoning about trust andrisk involved in interactions between users. Trust, therefore, controls theamount of information that can be revealed, and risk analysis allows us toevaluate the expect ....etc

Contention-Aware Performance Analysis of Mobility-Assisted Routing
Jindal, A. Psounis, K. Dept. of Electr. Eng., Univ. of Southern California, Los Angeles, CA;
This paper appears in: Mobile Computing, IEEE Transactions on Publication

Abstract
A large body of work has theoretically analyzed the performance of mobility-assisted routing schemes for intermittently connected mobile networks. But the vast majority of these prior studies have ignored wireless contention. Recent papers have shown through simulations that ignoring conte ....etc

CAR: Context-Aware Adaptive Routing for Delay-Tolerant Mobile Networks
Musolesi, M. Mascolo, C. Dept. of Comput. Sci., Dartmouth Coll., Hanover, NH;
This paper appears in: Mobile Computing, IEEE Transactions on Publication

Abstract

Most of the existing research work in mobile ad hoc networking is based on the assumption that a path exists between the sender and the receiver. On the other hand, applications of decentralised mobile systems are often characterised by network partitions. As a consequence delay tolerant networking ....etc
