Self organization is an important phase of a wireless sensor network. After deployment, sensors nodes are required to self organize themselves to form a network of their own. Security is an important aspect while forming the network. Only the authorized nodes should be allowed to join the network. For implementing security such as confidentiality, integrity(More)
Network availability is a very important need of any production environment. Unfortunately due to many reasons a link in a wide area network does not have consistent availability for a long period of time. Hence an application needs to be designed considering this unreliability factor of a wide area network. However, such network instabilities are not seen(More)
Self organization is an important phase of a wireless sensor network. Thousands of Sensors are deployed in a large geographical area randomly without considering the location factor. After deployment, sensors nodes are required to self organize themselves to form a network of their own. How well the network is formed determines the life of the whole network(More)
Performance testing of a multi-tiered Web application in real WAN is not a trivial job. In this circumstance a tool which brings WAN cloud to a local area network makes the life of a developer/tester easier. However, mere emulation of WAN inside a LAN does not help a tester, unless he gets to know the performance of the applications in some numbers.(More)
Non-intrusive remote monitoring of data centre services should be such that it does not require (or minimal) modification of legacy code and standard practices. Also, allowing third party agent to sit on every server in a data centre is a risk from security perspective. Hence, use of standard such as SNMPv3 is advocated in this kind of environment.
