SPam over IP Telephony (SPIT) is an emerging threat in the telecom era of Voice over IP Networks (VoIP). Though evolved from email spam, SPIT is more obstructive and intrusive in nature as they require response from the callee. Contemplating the behavior of SPIT, a provider based system is contributed with the proposed mechanism installed on the SIP proxy server. In this work, a biologically inspired...
Voice over Internet Protocol (VoIP) has become a very popular technology as it allows the users to make phone calls over the public internet. Some of its predominant features such as efficiency, cost-effectiveness and long distance communication made VoIP to stand apart from the traditional Public Switched Telephone Networks (PSTN). Session Initiation Protocol (SIP) is the contemporary signaling protocol...

In mobile computing caching plays a vital role owing to its ability to alleviate the performance and availability limitations of weakly-connected and disconnected operations. An efficient way to reduce query delay, save bandwidth and improve system performance is to cache the frequently accessed data objects at the local buffer of a mobile. Owing to the disconnection and mobility of the mobile clients,...
Caching plays a key role in mobile computing because of, its ability to alleviate the performance and availability limitations of weakly-connected and disconnected operations. Caching frequently accessed data objects at the local buffer of a mobile is an efficient way to reduce query delay, save bandwidth and improve system performance. Classical cache management strategies may not be suitable for...
