Assessment of DSACC and QPART Algorithms in Ad Hoc Networks
The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...
متن کاملAd - Hoc Sensor Networks
s of wireless microsensors for monitoring vironments have emerged as an important new area for wireless technology. Key attributes of types of networked systems are the severely computational and energy resources, and an rational environment. This paper is a study of nication security aspects of these networks. imitations and specific architecture of sensor all for customized security mechanism...
متن کاملSecurity in Ad Hoc and Sensor Networks
Due to the recent development in mobile ad hoc networks and sensor networks, they are being used widely. Security in sensor networks has become a important research topic. Inherent properties of these networks like limited resources (like computing power battery power), dynamic topology, wireless vulnerabilities, multi-hop communication pattern, open air environment complicates providing securi...
متن کاملGeocasting in ad hoc and sensor networks
In a geocasting problem in ad hoc networks, a message is sent from one node to all the nodes located in a designated region. For example, monitoring center needs to contact all active sensors within a monitored area to either gather data from them periodically, or to provide its location to sensors covering certain area for event reporting. Intelligent flooding methods exist for this task when ...
متن کاملBroadcasting in Ad Hoc and Sensor Networks
We consider dynamic wireless networks in which each node has the same and fi xed transmission range. Ad hoc wireless networks are considered in conference, rescue, and military scenarios, while small size battery powered sensor networks are envisioned for monitoring the environment, with individual sensors reporting observed events (movement, temperature, chemicals, etc.) to a base station. The...
