Title : WMNs: The Design and Analysis of Fair Scheduling
Country : India
Authors : M. Sudhakar || Vandana Khare

Abstract: In this paper an attempt has been made to address the matter of scheduling in wireless mesh networks. First, we offer a comparison of existing scheduling algorithms and then classify them based on the scheduling techniques in the degree of fairness and their implementation frameworks. Later we attempted good scheduling approach victimization multiple gateways. The projected scheduling approach consists of 4 necessary steps namely, demand tables, demand propagation in group generation and schedule generation. Simulation experiments area unit conducted to check the performance of fair scheduling with the strategy that doesn't use fair scheduling. The simulation results assert that the projected scheduling has superior performance with reference to the metrics used for performance analysis.

Title : Ndsp: Neighbor Assisted Distributed Self-Healing Protocol for Compromised Node Recovery in Wireless Sensor Networks
Country : India
Authors : Silochana Devi || RohitVaid

Abstract: Wireless sensors network (WSN) is collection of sensors nodes and a base station. All the sensor nodes in the network collect data from the environment and sent this data to the base station (BS). This data is transmitted in hope by hope fashion, i.e. each sensor sent the data to its one hope neighbor in the direction of BS on wireless medium. As themedium is wireless which is already less securedthus more prone to attacks. Therefore security is one of the major issues in WSN. An adversary is a node which steals information stored in the memory of sensor nodes. This paper presentsa neighbor assisted distributed self-healing protocol (NDSP) for compromised node recoveryin wireless sensor networks.

Country : India
Authors : Sara Salman SelimanAlsafi || Ashraf Gasim Elsid Abdalla || AminBabiker A/Nabi Mustafa

Abstract: This paper presents an algorithm for bandwidth management in integrated LTE network and WLAN. The proposed algorithm also suitable for multimedia network (image, telephone and videophone). A software tool is implemented to simulate the proposed algorithm it is basedon windows for random distribution numbers such as Poisson distribution functionfor traffic generation and uniform distribution for mobile location using MATLAB. The parameters taken in this proposed simulation model are: number of user, type of traffic, user class and user bandwidth. The results of the simulation indicate that the new algorithm increases the bandwidth availability in the lower data rate network and this reduces the congestion in the high data network.

Title : Incorporation of GlobalIssue factors in SDLC by using Inverse Requirement
Country : Pakistan
Authors : Maham Tariq || Akmal Rehan || Raheela Nasim

Abstract: Approval of the project depends on the user's fulfillment and that is just accomplished when the item satisfies client's necessities and requests. Accuracy of necessities assumes a critical part in software development. In the event that the prerequisites are not clear or not totally gathered then the actual product can't be accomplished. The research portrays that the vast majority of the engineers focus just to the organizational needs or to the functionalities of the requested product and less to the user's prerequisites or interface requirements with which user needs to connect. Software Engineering (SE) manages the "workable product", and the research shows that the primary center of Software Engineering (SE) manages the "Functional Requirements".
