he dynamic probability admission control policy for distributed video provides a method that decides in a Video on Demand (VOD) system which content requests can be admitted and which requests should be rejected to maintain Quality of Service (QoS). Requests for popular and expensive movies should not be rejected on the behalf of unpopular movies to generate more revenue. The dynamic probability admission control policy combines a shared resource admission control and a class-based admission control.

A cooperative packet routing for wireless sensor networks is described. In one aspect, a transient sensor node in a wireless sensor network receives a packet from a source node, wherein the packet is targeted for receipt by a base station. The transient sensor node, responsive to receiving the packet, estimates how much operational energy remains in the sensor node. If the determined amount of energy meets a configurable threshold, the transient sensor node implements a set of cooperative packet routing operations for conditional re-transmission of the packet to the base station.

Climate change poses a great challenge to the international community. This has led to a number of global initiatives to mitigate human actions that negatively affect the climate. Among the most prominent are sustainable development initiatives. The central pillars of such initiatives are education, training, and research; these pillars are essential to raise awareness and expand the parameters of sustainable development. The purpose of this paper is to explore to what extent climate change and sustainability issues are addressed in higher education institutions in Saudi Arabia.
