AD HOC WIRELESS NETWORK ARCHITECTURE AND PROTOCOLS PDF

Note that, whereas in the hard-type handover the number of resources uti- lized remains unchanged, in the soft-type handover this is not true. In the hard-type handover, the new resource is utilized only after the old resource has been released. In the soft-type handover, a communication with more t[r]

4.3. Radio transmitter
Figure 12 shows the radio transmitter utilization for DSR, AODV, and TORA protocols. TORA uses a lot of packets to create, maintain, erase, and optimize routes for the ra- dio transmitter link. As a result, TORA performs better than AODV and DSR f[r]

A logically separate version of TORA is run for each destination to which routing is required. The following discussion focuses on a single version running for a given destination, j. TORA can be separated into three basic functions: creating routes, maintaining routes, and er[r]

Ramanathan and Rosales-Hain evaluate the performance of their protocols in mobile ad hoc networks through simulation, considering several performance metrics such as (i) packet delivery ratio; (ii) packet delay; and (iii) average and maximum node transmit po[r]

resultant metric can then by large reflect the expected number of transmission slots that one new arriving packet should wait before it gets transmitted.
Although current coding-aware routing protocols, like DCAR, are able to discover coding-possible routes, they lack a mechanism to condu[r]

In a wireless ad hoc network, messages are transmitted, received, and forwarded in a finite geometrical region and the transmission of messages is highly dependent on the locations of the nodes. Therefore the study of geometrical relationship between nodes i[r]

27.1 Introduction to Multimedia Mobile Ad Hoc
Communications
M obile communications computing has enjoyed an explosive growth that began in the late 1990s and is expected to continue well into the new millennium. As more and more users are becoming mobile [23], mobil[r]

Topology issues should receive more and more consideration in Wireless Sensor Networks (WSN). While the supplied underlying network topology typically optimizes WSN applications, another inclination is observed to optimize WSN employing topology control. In the current ten years, wireless sensor net[r]

When considering the installation of a network in an existing facility, wireless is at the top of many an administrator’s lists of options. A simple wireless network can be up and running in just a few minutes after the workstations are turned on. Connectivity t[r]
