Wireless mesh networking is a promising technology that can support numerous multimedia applications. Multimedia applications have stringent quality of service (QoS) requirements, i.e., bandwidth, delay, jitter, and packet loss ratio. Enabling such QoS-demanding applications over wireless mesh networks (WMNs) require QoS provisioning routing protocols that lead to the network resource underutil...

Geographically distributed (geo-distributed) datacenters for stream data processing typically comprise multiple edges and core connected through Wide-Area Network (WAN) with a master node responsible allocating tasks to worker nodes. Since WAN links significantly impact the performance of task execution, existing assignment approach is unsuitable low latency high throughput demand. In this pape...

DTLS is becoming the de facto standard for communication security in the Internet of Things. In order to run the DTLS protocol one needs to establish keys between the communicating devices. The default method of key establishment requires X.509 certificates and a Public Key Infrastructure, an approach which is often too resource consuming for small IoT devices. DTLS also supports the use of pre...
