This paper focuses on how the probability can affect on the ad hoc routing protocols and especially on AODV regarding energy consumption. The evaluation of the performance of AODV with different message forwarding probability based on the mechanism that AODV protocol uses in order to forward the message in all nodes of the network. The evaluation of AODV protocol was carried out using network simulator-2...
Simulation platforms have become important tools in the design and evaluating of protocols for Wireless Sensor Networks. Thus the use of realistic models in simulation is important for the development of protocols. However, most of the reported studies based on simulations tend to use simple or non-realistic parameters and assumptions. This paper proposes a transmit power control algorithm with a...
In recent years, there have been a number of reported studies on the design of communication protocols using simulation platform. However, most of the reported works were evaluated using simple or idealistic wireless communication channel modeling. Experimental results have shown that the characterization and modeling of wireless communication channel is important to achieve a successful implementation...
With the emergence of pervasive environment, mobile recommender needs to make use of user in-time contextual information to provide personalized recommendation. In this paper, a proactive context-aware news recommender in mobile hybrid P2P network is designed and implemented. We develop a general Analytic Hierarchy Process (AHP) model through empirical studies. We discuss how the relative weight of...
Context-aware computing benefits mobile applications by adapting systems behavior through user surrounding. However, contextualized information retrieval for mobile user in mobile P2p environment still remains a challenging problem. In this paper, we present JHPeer framework for mobile information retrieval (IR) in hybrid peer to peer (P2P) networks. JHPeer incorporates context engine to fit on mobile...
With the emergence of pervasive computing environments, mobile information sharing and retrieval is becoming an exciting domain that challenges information scientists. In this paper, we describe a hybrid peer to peer context-aware framework for building mobile information sharing applications. A scalable and flexible architecture based on JXTA is presented. The architecture called "JHPeer"...
