Problem statement: Multicasting communication network accepted a single message from an application and delivered copies of the message to multiple recipients at different locations. Recently, there has been an explosion of research literature on multicast communication environment. The objective of this study were to contribute the complexity of supporting current multicast applications, (i) t...

Recently, vehicular ad-hoc network (VANET) has emerged as an excellent candidate to change the life style of the traveling passengers along the roads and highways in terms of improving the safety levels and providing a wide range of comfort applications. Due to the foreseen impact of VANETs on our lives, extensive attentions in industry and academia are directed towards bringing VANETs into rea...

Mobile nodes in military environments like a field of battle or a hostile region ar seemingly to suffer from intermittent network property and frequent partitions. Disruption-tolerant network (DTN) technologieshave become eminent solutions that enable wireless devices carried by troopers to speak with one another and access the guidance or command faithfully by exploiting secondary storage node...

Wireless sensor networks have been widely deployed in many applications, e.g., military field surveillance, health care, environment monitor, accident report, etc. Each sensor detects a target within its radio range, performs simple computations, and communicates with other sensors. Generally, sensors are constrained in battery power, communication, and computation capability; therefore, reduci...
