p-cycles are a fairly recent addition to the set of basic approaches for transport networks survivability. The main attraction of p-cycle is that it combines the ring-like speed with mesh-like efficiency. p-cycles networks are guaranteed to be protected against single fiber duct failure. However, it is incompetent to provide protection on subsequent(More)
Semantic service trading is powerful mechanism in order to allow devices sharing resources and services in highly dynamic environment Mobile devices are able to spontaneously form highly dynamic Ad-hoc networks allowing for communication even when no infrastructure exists. These types of networks enable the participating devices to share resources and(More)
In recent years, p-cycles have been widely investigated for survivability of WDM networks. They provide fast recovery speed such as ring and capacity efficiency as mesh survivability schemes. However, restoration paths are very long, which causes excessive latency and intolerable physical impairments. On the other hand, nowadays, a wide set of applications(More)
Broadly speaking a term Cryptography used to secure & hide the original information of a message from the unauthorised users. First time used to encrypt a plaintext into cipher text where a key was associated at the time of encryption to change original content into some other form i.e. decrypted message. And same key was used to decrypt that message into(More)
Congestion control in wireless networks has been extensively investigated over the years and several schemes and techniques have been developed, all with the aim of improving performance in wireless network. With the rapid expansion and implementation of wireless technology it is essential that the congestion control problem be solved. This paper presents a(More)
Today's smart vehicles are embedded with computer, GPS receivers, short range wireless network interfaces make capable vehicles to communicate with their neighbour vehicles. Thus, they form a self organizing, self managing with low bandwidth network. This type of network called vehicular ad hoc network (VANET). VANET is a wireless communication area in(More)
Today, the most promising technique used for the survivability of optical transport networks is p-cycle. However, it provides longer restoration path at failure state of the network. The intercycle switching (ICS) is one of the recent approaches that is based on idle p-cycles and is used for shortening the length of restoration path in single-fault model.(More)
