Abstract.
M{commerce is a new area arising from the marriage of elec-
tronic commerce with emerging mobile and pervasive computing tech-
nology. The newness of this area|and the rapidness with which it is
emerging|makes it dicult to analyze the technological problems that
m{commerce introduces|and, in particular, the security and privacy is-
sues. This situation is not good, since history has shown that security
is very dicult to retro{t into deployed technology, and pervasive m{
commerce promises (threatens?) to permeate an ....etc

Abstract
Recent advances in hardware, software, and communication technologies are enabling the design and implementation of a whole range of different types of networks that are being deployed in various environments. One such network that has received a lot of interest in the last couple of years is the Vehicular Ad-Hoc Network (VANET). VANET has become an active area of research, standardization, and development because it has ....etc

Energy-Efficient Routing in Mobile Ad Hoc Networks: Mobility-Assisted Case (Java)
IEEE Transactions on Vehicular Technology, Vol. 55, No. 1, January 2006

Abstract:
Because of node mobility, mobile wireless networks experience rapid variations in the channel strengths, which could potentially be exploited for more cost-effective communications. The pioneering work by Grossglauser and Tse first demonstrated that a network under sufficient amount of random mobility can provide a larger scaling rate of capacity than a static network, a ....etc

Abstract—We investigate the communication range of the nodes necessary for network connectivity, which we call bidirectional connectivity, in a simple setting. Unlike in most of existing studies, however, the locations or mobilities of the nodes may be correlated through group mobility: nodes are broken into groups, with each group comprising the same number of nodes, and lie on a unit circle. The locations of the nodes in the same group are not mutually independent, but are instead conditionally independent given the location of the group. W ....etc

ABSTRACT

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Position based routing protocols are becoming popular due to advancement and availability of GPS devices. One of the critical issues of VANETs are frequent path disruptions caused by high speed mobility of vehicle t ....etc

Abstract—
The Particle Swarm Optimization (PSO) algorithm,as one of the latest algorithms inspired from the nature, wasintroduced in the mid 1990s and since then, it has been utilizedas an optimization tool in various applications, ranging frombiological and medical applications to computer graphics andmusic composition. In this paper, following a brief introductionto the PSO algorithm, the chronology of its evolution ispresented and all major PSO-based methods arecomprehensively surveyed. Next, these methods are studiedseparately an ....etc
