Many studies have been conducted on Handwritten Signature Verification. Researchers have taken many different approaches to… Expand Signature verification is an important biometric technique that aims to detect whether a given signature is forged or genuine. It… Expand In this paper, the session setup delay of the session initiation protocol (SIP) is studied. The transmissions on both the forward… Expand This paper reports the design of a push-to-talk service operated over a GPRS/UMTS network (push-to-talk over cellular - PoC). The… Expand SIP and SDP are used in 3G cellular IP multimedia subsystems (IMS) to perform multimedia session setup and maintenance. However… Expand This document describes a mechanism that allows Signaling Compression
(SigComp) implementations to report precise error… Expand Link adaptation technology has been introduced in new generation transmission systems such as 3-G or 4-G optimizing both their… Expand This document defines Signaling Compression (SigComp), a solution for compressing messages generated by application protocols… Expand The purpose of this document is to outline requirements and motivations for the development of a scheme for compression and… Expand This paper demonstrates the efficiency gains achievable for the compression scheme SigComp using extended operations where… Expand
