Women’s Leadership in Science, Technology, Engineering & Mathematics:

Despite gains overall, women are still under-represented in leadership positions in science, technology, engineering, and mathematics (STEM) fields. Data in the US suggest around onequarter of deans and department heads are women; in science this drops to nearly 1 in 20. Part of this problem of under-representation stems from the population pool: only 33% of science and engineering doctorate ho...

This paper proposes a transformation scheme for rendering the asymmetric watermarking technique into its asymmetric version. The asymmetric technique uses secret watermark as private key and public watermark as public key. The public watermark has a normal distribution and the private watermark is a linear combination of the public watermark and a secret sequence. The detection process is imple...

Data security has become a major issue in most network protocols. For wireless system, security support is even more important to protect the users as well as the network. Due to this importance, different protocol were designed & deployed with network standards in order to add the security. The security sub layer of IEEE 802.16 employs an authenticated client/server key management protocol in ...

This paper proposes a new multicast protocol for Mobile Ad Hoc networks, called the Multicast routing protocol based on Zone Routing (MZR). MZR is a source-initiated ondemand protocol, in which a multicast delivery tree is created using a concept called the zone routing mechanism. It is a source tree based protocol and does not depend on any underlying unicast protocol. The protocol’s reaction ...
