opping Spread Spectrum FHSS
In Frequency Hopping the transmission band is divided into dierent frequency channels typically 
and a logical channel ie a channel on which two or more devices communicate hops periodically from
one frequency channel to another with a pseudorandom hopping sequence

Also in Direct Sequence the frequency band is divided into fewer but larger
channels but no hopping
is used To compensate for noise on a channel a technique called chipping is implemented each bit is

MOBILE COMPUTING LOCATION MANAGEMENT


Introduction
Managing location information of mobile nodes is an important issue in mobile computing systems. Location management is one of the fundamental issues in cellular networks. It deals with how to track subscribers on the move and how to update his or her movements. In mobile communication environment, they are going to accommodate more subscribers; the size of the cell must be reduced to make more efficient use of the limited frequency spectrum allocation. This will add to the challenge of some fundamental issues in cell..................==> [ Click Here to Read More ]

ARCHITECTURE, CHALLENGES AND RESEARCH ISSUES ON MOBILE COMPUTING

Abstract

With the advent of the Internet and the plurality and variety of fancy applications it brought with it, the demand for more advanced services on cellular phones increasingly becoming urgent. Unfortunately, so far the introduction of new enabling technologies did not succeed in boosting new services. The adoption of Internet services has shown to be more difficult due to the difference between the Internet and the mobile telecommunication system. The goal of this paper is to examine the characteristics of the mobil..................==> [ Click Here to Read More ]
