Wireless Sensor Network (WSN) is widely used for monitoring and gathering data in an autonomous fashion. Since sensors are small and power constrained devices, it is the most important to minimize the energy consumption. The authors propose energy efficient zone routing protocol with multi-gateway for enhancing life time performance of wireless sensor networks. In this ...

Now-a-days, online social networking websites are used frequently. These websites are well-known as social sites. Social networking websites work corresponding to an online society of internet users. Online Social networks are networking sites which permit users to communicate with each other and transmitting valuable data from one to another. One time they turn into an ...

Mobile Ad hoc NETworks (MANETs) plays an important role in emergency communications, where network must build up temporarily and quickly. Since the nodes move randomly, routing protocols must be very effective and reliable guarantee successful packet delivery. Based on the data delivery structure, most of the existing multicast routing protocols can be divided into two ...

Today’s computational advances have created numerous applications for I/O operations have the capacity to store more data. The authentic need is accessible of information from anyplace. This gets to be issue for some clients who use applications, for example, databases, media and hard disks and so forth. The I/O data solicitations of these applications get ...

In the last few years, processing multimedia data in Wireless Sensor Networks (WSNs) has become a promising technology. Generally, wireless sensor network has set of sensor nodes that are powered by small irreplaceable batteries. These sensor nodes are smartly positioned in the area to be monitored. It will sense the environmental behaviors and transmit data ...

Test Driven Design (TDD) and Design Driven Testing (DDT) are used for test case generation. TDD generates so many duplicated test cases at the end of the project. DDT is novel approach to generate test cases based on design model of application. Comparative study indicates batter result using DDT. White-box traditional regression testing depends on ...

Cyber crime is the unlawful act wherein the computer is either a tool or a target or both. Cyber crime is the evil act done by the hi-tech professionals, some, as hobby and as business. In this paper, authors keeping the view in the mind that prevention is better than cure, have describes some preventive ...

Significant portion of cache energy in a highly associative cache is consumed during tag comparison. In this paper tag comparison is carried out by predicting both cache hit and cache miss using multistep tag comparison method. A partially tagged bloom filter is used for cache miss predictions by checking the non-membership of the addresses and ...
