Buffer aware routing in interplanetary ad hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Recent research has shown that existing TCP/IP protocol suit exhibits poor performance in space communication networks. To deal with communication challenges in deep space such as long propagation delay, high channel error ...
Cache performance evaluation in DSR protocol through cross-layering for mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Wireless mobile ad-hoc networks are being actively studied by many researchers these days. These networks are suitable to be used in various situations because of (i) their infrastructure-less property and (ii) the mobility ...
Scalable routing in mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
In Mobile Ad Hoc Networks (MANETs), performing routing is a challenging task in presence of the varying network parameters like node mobility, traffic and network size. It is very important to analyze the scalability ...
Testbed based experimental analysis of transport protocols over wireless ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Ad hoc networks are networks with no infrastructure and self-organized in nature. ad hoc networks allow nodes to form network when they come into range of each other provided nodes are configured in ad hoc mode. But these ...
Localization for a habitat monitoring sensor network for ground turtles
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis work deals with the localization problem (i.e. finding the location of the sensor nodes) in sensor networks. This work is specifically concerned with the localization of the sensor nodes on small ground turtles ...
Security analysis of two fair exchange protocols
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
E-commerce applications enable two parties to exchange digital items electronically. It is critical for such applications that the underlying protocols ensure the fairness requirement: no honest participant should suffer ...
Comparative study between exponential back off and dynamic waiting strategies for medium access in wireless ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
IEEE 802.11 DCF (IEEE 802.11 Distributed Coordination Function) is widely used MAC protocol for wireless channel access. Although it is developed for single hop networks where all nodes are in the same radio range, it can ...
Network coding based multicast in delay tolerant networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Delay Tolerant Networks (DTN) are sparse ad hoc networks in which no contemporaneous path exists between source and destination most of the time. In DTN, connectivity graph of the network changes over time either due to ...
Analysis of address allocation protocols for mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
In almost all networks, it is necessary to have a unique identifier for each node. This identifier is used to find out route locating a particular node. So an address is must for any node for unicast communication. Addresses ...
Cooperation enforcement mechanisms in wireless adhoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Wireless adhoc networks are autonomous, infrastrutureless networks where there are no dedicated routers or base stations and nodes are expected to cooperate in Wireless performing routing duties to keep network connected. ...
