In Mobile Social Networks(MSN) individuals with similar interests or commonalities, connect to each other using the mobile phones. Validation of protocols for these networks relies almost exclusively on simulations. Thus a simulation using a mobility model that captures the behavior of nodes in the real world is needed. The current simulations techniques use random models to generate dynamic MSN....
This work proposes the use of a weighted Finite State Machine to serve as a computational model for analyzing the performance of communication protocols. The new model's use is demonstrated by concentrating on web-based services, Internet level-5 protocols in particular, because when the latter are ported onto mobile handsets, fail to meet performance expectations. The same modeling technique can...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
