BANDWIDTH ESTIMATION FOR IEEE 802.11 BASED ADHOC NETWORK-MOBILE COMPUTING

Abstract: Since 2005, IEEE 802.11-based networks have been able to provide a certain level of quality of service (QoS) by the means of service differentiation, due to the IEEE 802.11e amendment. However, no mechanism or method has been standardized to accurately evaluate the amount of resources remaining on a given channel. Such an evaluation would, however, be a good asset for bandwidth-constrained applications. In multihop ad hoc networks, such evaluation becomes ev ....etc

Preface
A large class of routing protocols for MANETs, namely, reactive protocols, employs some form of caching to reduce the no. of route discoveries .the simplest form of caching is based on associating a timeout with each cache entry.
Such timer based cache scheme can increase the protocol efficiency. However the timeout is not well tuned, a sever performance degradation arises as entries are removed either too early or too late from the cache .
In this paper, we address the problem designing a proactive protoc ....etc

Abstract:
To secure a mobile ad hoc network (MANET) inadversarial environments, a particularly challenging problem is how to feasibly detect and defend possible attacks on routing protocols, particularly internal attacks, such as a Byzantine attack. In this paper, we propose a novel algorithm that detects internal attacks by using both message and route r ....etc

Abstract

Recently natural disasters such as earthquake, tsunami, typhoon and hurricane in addition to annual disaster have frequently happened at many places around the world. Once disaster happened, communication network and information system are seriously damaged and communication means for residents cannot be used in the disaster area.
Therefore, it is required to prepare emergency network system which can be quickly reconstructed to recover from the network failure and used to confirm resident’s safety and damaged a ....etc

ABSTRACT
Smart spaces are composed of smart and dummy nodes
which act as the source for providing service. A large
number of cluster groups are formed in the smart space.
Some of these smart spaces are mobile, some are Adhoc
and others are sensor ....etc
