Performance Analysis of Cluster BasedProtocols in Sensor Networks and theirVulnerabilities

Wireless sensor networks as gained lots of impact in the real time applications like monitoring, surveillances and tracking. These applications are mainly rely on the collection of critical information where manual information collection is very difficult task. WSNs are more vulnerable to many types of threats, providing security will be very complex due to the resource constraint sensors. The proposed work aims to study and analyze the vulnerabilities and its effect on the performance of sensor networks in cluster based routing protocols. An exhaustive analysis is presented by captivating the standard clustering architecture with its different stage of operating modes. A comparison is done for with latest existing security solutions which mainly deal with cluster based protocols in wireless sensor networks. An Open Systems Interconnection layer wise comparison is presented with the possible vulnerabilities at each layer. This work also enlightens the literal need of security and its requirements in wireless sensor networks for an efficient information system

An Adapter based Network Management Layer Framework for provisioning Telecom Services

The provisioning of telecom services requires the subscribers and service related information to be provisioned onto the network elements. The network elements or element management systems store the information received and is used for activation of the services for the subscribers. These telecom services could be wire-line or wireless based services. All the telecom service providers are rapidly shifting to Next Generation Networks (NGN) which are IP based packet networks. NGNs are independent of the underlying transport technology, hence it does not matter whether the underlying hardware technology is wire-line or wireless based. This enables the service providers to focus on defining new telecom services which could be delivered to customers. Thus, there arises competition between service providers in creation and provision of services to customers as quickly as possible. Also, quick customization of services that are already provided to the customers based on their needs is a major requirement. Hence, the challenge of delivering services by provisioning them quickly on the network is to be addressed as the users scale in numbers. As a part of addressing this challenge, there is a need for effective communication with the network elements for provisioning. A framework that can integrate with multiple Service Order systems, transform their requests into network commands and techniques used to communicate efficiently is mentioned. The commands are generated suitably for the network element and communicated to it based on SOAP protocol. It can work with network elements that expose an interface using Web Service Description Language (WSDL).
