— Multi-Protocol Label Switching is useful in managing multimedia traffic when some links are too congested; MPLS Traffic Engineering is a growing implementation in today's service provider networks. In This paper we propose an improvement of MPLS-TE called EMPLS-TE, it is based on a modification of operation of Forwarding Equivalence Class (FEC) in order(More)
The steeping chip weighting waveforms are used in Multiple Access Interference cancellation by emphasizing the received spreading signal, therefore, that allows to solve the problem of orthogonality for the chip waveforms. The goal of this study was to elaborate a useful method based on fuzzy systems to determine the despreading sequences weighted by the(More)
The exponential chip weighting waveforms have been designed with the purpose of multiple access interferences (MAI) rejection based on the concept that the optimum despreading sequence in reference emphasizes the transitions in the received spreading signal of interest. The despreading sequence weighted by exponential chip waveforms was determined by only(More)
IPv6 is a next-generation Internet layer protocol designed by the IETF (Internet Engineering Task Force) to solve the problem of IP address depletion under the current Internet layer protocol. It has been developed to replace the current Internet Protocol version 4 (IPv4). Various operating systems support IPv6 protocol stacks and network infrastructures(More)
The QoS routing generates a significant number of control messages (overhead), which are necessary for the discovery and maintenance of routes. Indeed, the nodes must establish a mechanism to store and update the link-state in a mobile environment. This mobility in ad-hoc environment makes maintaining the link-state very difficult and costly. In addition to(More)
Mobile Ad hoc Network (MANET) is nothing but group of radio devices communicating with each other without using any physical infrastructure. MANET is widely used in day to day life applications, hence it is required that such network should perform efficiently. Efficiency of MANET is mainly depends on use of routing protocols. The efficiency of routing(More)
