Problems solved by technology

In addition, a larger hop count increases the chance of wireless signal interference, which adversely affects its own stream delivery (self-interference) and other established connections (cross-interference), and reduces overall system capacity
However, hop count is not the only factor determining path quality

Embodiment Construction

[0019] Given MAP as infrastructure in WMNs, and advances in processing power and storage, the present invention caches content (audio, video, and / or multimedia content) at selected wireless mesh access points or connects cache servers with wireless Selected MAPs in the mesh network are co-located in order to increase system capacity for video / multimedia services and ensure high content service quality. In addition, the present invention uses peers in a best-effort manner, if possible, to balance the workload on the network and reduce resource consumption along the path between the source and the sink / client device / end device.

[0020] The main difference between the architecture of the present invention and the existing Internet CDN scheme is:

[0021] 1. The client device in the present invention can simultaneously form a P2P relationship with the MAP content cache server and other peer devices and form a client-server relationship with the MAP cache server.

[0022] 2. The ...

Abstract

A method and apparatus for receiving content over a wireless network are described, including determining a first server from which to receive a content clip to be streamed, requesting the content clip to be streamed from the selected first server, receiving the streamed content clip from the selected first server, determining a peer device from which to receive a content clip to be downloaded, requesting the content clip to be downloaded and receiving the downloaded content clip. The first server is a mesh content server.

Description

technical field [0001] The present invention relates to wireless mesh networks, and more particularly to the use of infrastructure multi-hop wireless mesh networks to deliver high quality content services to client devices. Background technique [0002] Traditionally, content is streamed to end users over the Internet either directly from a content origin server or indirectly via an edge server in a content delivery network (CDN). By deploying many edge servers strategically located at the edge of the Internet, the CDN approach can reduce traffic across the network, reduce startup delays for users, and improve viewing quality for users. P2P content streaming has emerged as an alternative due to lower server infrastructure costs. By utilizing the resources of participating users / peers (upload bandwidth, storage space, processing power, etc.), the resources available in a peer-to-peer system grow proportionally to the number of users / peers. " / " is used here to denote an alte...
