Energy conservation is a very important design issue and has been attracting a lot of attention in recent years. The typical Mobile Ad Hoc Networks (MANET) routing protocols of the Internet Engineering Task Force (IETF) are mainly the shortest path routing protocols and do not consider the energy aware issue. This paper describes improvement of the(More)
In today's context, it is common to leave the house unattended as people are busy catching up with their tight daily schedule. Therefore, most people have chosen the home security system as the most reliable way to protect their home. However, the existing security mechanism provided by smart home is lack of intelligence for higher level decision making and(More)
In this paper, we propose an enhancement to the conventional Round Robin DNS load balancing technique which allows a single domain name to be associated with several web server IP addresses in a rotated order in a server cluster. Once the DNS server resolves the domain name to one of the web server IP address, the subsequent requests from the same client(More)
High latency network is increasingly important in today's telecommunication world. It is widely used for real-time interactive multimedia applications such as video, music, data and graphic files exchange. One example of this network is the satellite communication technology. Unfortunately, the high latency satellite network provides limited network(More)
A wireless ad hoc network is an unpredictable network as the connections between nodes are not static. They consist of multiple network nodes that work together cooperatively without any intervention of a centralized management. Having such a dynamic nature naturally brings uncertainties in the ad hoc network such as the state of the links in between nodes(More)
The new opportunities opened up by wireless technologies are also accompanied with new technical challenges. Principal among the challenges is the fact that wireless medium has limited bandwidth resources when compared with wired equivalent. The convenience brought about by the IEEE 802.11n protocol is also followed by the technical challenge of near(More)
Blind users have very low vision to interact with the world. Information accessibility is always a problem to them. The traditional application form filling task can always be difficult for them to accomplish. In a lot of cases, they rely on Braille technology or assistant from a sighted people in order to fill the form. As the Internet gets popular with(More)
As Internet Protocol version 4 (IPv4) addresses deplete, Internet Protocol version 6 (IPv6) is introduced to alleviate the depletion with introduction of much needed functionality in security and so much more. Quality of Service (QoS) has been one of the aspects taken into consideration for improving network performance such as Packet Delivery Fraction(More)
— The lifetime of Wireless Sensor Networks (WSNs) were limited by the fact that sensor nodes are battery-powered and communication is the main source of energy consumption. Once deployed, the entire network lifetime shows a strong dependency on the battery lifetime of individual nodes. Therefore, WSNs can only subsist on while the battery power is adequate.(More)
