On routing protocols using mobile social networks
A Mobile Social Network MSN is defined as a mobile network that uses social relationships to determine node communication. Many wireless networks including ad hoc networks do not reflect a real world deployment because of routing implementation ...
Joint cooperative analog network coding and OFDM system for wireless communication networks
In wireless mobile communication networks, network coding and cooperation are the promising techniques to increase the spectrum utilisation efficiency. OFDM is also one of the most efficient modulation techniques to deal with multipath fading channel ...
Hybrid local search polynomial-expanded linear multiuser detector for DS/CDMA systems
This work proposes a new multiuser detector for DS/CDMA systems constituted by the polynomial Minimum Mean-Squared Error MMSE detector followed by a local search algorithm 1-adapt LS one-adaptive local search, namely the hybrid 1-adapt-LS-MuD. In ...
An efficient scheduling scheme based on MET for MIMO systems
An efficient multi-user scheduling scheme is proposed to increase the throughput of the system and guarantee the fairness to all the users. In each timeslot, the product factor of each user is updated by the requested data rate and the increment of the ...
A kind of two-stage RRT algorithm for robotic path planning
In order to solve the problem of motion planning with dynamics, RRT algorithm was proposed. But with the environment becoming complex, the tree exploration slows down significantly. In this paper, a novel two-stage motion planning is proposed. The first ...
Handoff self-management based on SNR in mobile communication networks
In today's high density wireless networks, delay is considered one of the main factors limiting the capacity and increasing the new call blocking probability of a cellular system. In this paper we discuss and analyse a delay scenario in cellular ...

To make up for the shortage of the dwMDSG algorithm on the positioning accuracy and convergence performance, this paper proposes a multidimensional scaling localisation algorithm based bacterial foraging optimisation. Firstly, MDS Multidimensional ...
An evolvable cellular automata based data encryption algorithm
This paper proposed a new data encryption algorithm based on evolvable cellular automata CA, by taking the CAs' initial state and rule as the evolution object, try to find out the cipher text which is close to the plaintext after evolution by CAs. ...
Video stabilisation using local salient feature in particle filter framework
A novel digital video stabilisation approach that uses salient features and particle filter for global motion estimation is proposed in this paper. In this approach, the local salient features are first gained by the improved K-means clustering method ...
An efficient service selection framework for pervasive environments
Pervasive computing enables the user to connect to the network and receive any service anywhere any time. The problem of satisfying the user's request as per their requirements is a vital process. There can be many service providers providing the ...
Attack trace generation of cryptographic protocols based on coloured Petri nets model
In this paper, we propose a practical model checking methodology for the analysis of key exchange confidentiality property and authentication property of cryptographic protocols modelled by Coloured Petri Net CPN; and propose a new attack trace ...
