abstract: gridlock is an extreme traffic state where vehicle cannot move at all. this research studies the development of gridlock by theoretical and numerical analysis. it is shown that the development of gridlock can be divided into several stages. the core of the development is the evolution of congestion loop. a congestion loop is comprised of a number of consecutively connected spillover l...

In wireless communication networks, the load balancing mechanism can improve the frequency utilization and reduce the outage rate. Furthermore, the user cooperation is used to enhance the SNR of the edge user. Therefore, in cooperative wireless communication network, the cooperation probability is introduced in the handover decision function of existing load balancing mechanisms which are based...

Introduction: Cooperative communications [1] create diversity gains for network users with a single antenna. The classical cooperative scheme consists of two orthogonal time slots (TS): a broadcasting TS for a source (S) to transmit its signal to the intended destination (D), and a relaying TS for a relay (R) to retransmit S’s signal to D. There are amplify-and-forward (AF) and decode-and-forwa...

Cooperative communication can achieve spatial diversity gains, and consequently combats signal fading due to multipath propagation in wireless networks powerfully. A novel complex field network-coded cooperation (CFNCC) scheme based on multi-user detection for the multiple unicast transmission is proposed. Theoretic analysis and simulation results demonstrate that, compared with the conventiona...

This work proposes a method for integrating cooperative behaviors among distributed autonomous agents based on local communications. The presented architecture is reactive-based to ensure self-organization, reactivity and adaptability of the agents. Animal signal spreading have interesting characteristics such as spatial limited communication, intensity meaning, redundant information (robustnes...

Transnational crime, sometimes called international crime or multinational systemic crime, is more than an extension of domestic crime. In the context of globalization, transnational organized crime groups respond to market incentives and operate with cooperative relationships, which makes the multinational criminal systems become more efficient and powerful. As a result, no single country has ...
