Achievable secrecy rate analysis in mmWave ad hoc networks with multi‐array antenna transmission and artificial noise

Secrecy Transmission Capacity in Noisy Wireless Ad Hoc Networks

This paper considers the transmission of confidential messages over noisy wireless ad hoc networks, where both background noise and interference from concurrent transmitters affect the received signals. For the random networks where the legitimate nodes and the eavesdroppers are distributed as Poisson point processes, we study the secrecy transmission capacity (STC), as well as the connection o...

Assessment of DSACC and QPART Algorithms in Ad Hoc Networks

The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...

Performance of Transmission Rate Changing in Ad-Hoc Networks

Hunting-based Directional Neighbor Discovery in mmWave Ad Hoc Networks

The directional neighbor discovery problem, i.e., spatial rendezvous, is a fundamental problem in millimeter wave (mmWave) networks, where directional transmissions are used to overcome the high attenuation. The challenge is how to let the transmitter and receiver beams meet in space under deafness caused by directional transmission and reception, where no prior information or coordination is a...

Rate adaptive video transmission over ad-hoc networks - Electronics Letters

Introduction: Under best effort ad-hoc network environments where the routing and channel characteristics are expected to vary dynamically (e.g. mobility conditions), providing reliable multimedia services is becoming a challenge. A crucial factor affecting ad-hoc channel performance is the deterioration of the network throughput performance as the number of transmission hops increases [1]. Thi...
