Fault tolerance in wireless networks
A network includes a plurality of logical access entities. Each access entity includes one or more communication interfaces. The network further includes a plurality of logical node entities. Each logical node entity includes one or more communication interfaces that are configured to wirelessly communicate in a redundant manner with any of the logical access entities. In an embodiment, a communication degradation in the network is assessed, and the network is configured as a function of that assessment to provide fault tolerance within the network.
1. A tangible machine readable storage medium comprising instructions for executing a method comprising:
assessing an effect of a communication degradation between any of two or more logical communication entities of a network infrastructure;
configuring said network infrastructure as a function of said assessment;
wherein said infrastructure comprises redundant wireless communication between said logical communication entities, thereby providing fault tolerance within said network; and
wherein said redundant wireless communication comprises providing a plurality of non-overlapping communication channels to said logical communication entity;
selecting said redundant wireless communication channels as a function of communication signal parameters, said communication signal parameters including one or more of a signal to noise ratio, a received signal strength, network traffic density, and an acknowledgment of a failure; and
selecting said redundant wireless communication channels as a function of availability of one or more synchronization signals transmitted from one or more logical access entities.
2. The machine readable medium of claim 1 , wherein said redundant wireless communication further comprises wirelessly communicating to a logical access entity of said logical communication entity.
3. The machine readable medium of claim 2 , wherein said logical communication entity is within a basic service set of said wireless network.
4. The machine readable medium of claim 2 , wherein said logical communication entity is within an extended service set of said wireless network.
5. The machine readable medium of claim 1 , wherein said redundant wireless communication comprises wirelessly communicating to a node entity of said logical communication entity.
6. The machine readable medium of claim 1 , wherein said logical access entity comprises a wireless network interface card.
7. The machine readable medium of claim 1 , further comprising establishing a redundant communication path among said logical communication entities.
8. The machine readable medium of claim 1 , wherein said logical communication entity comprises middleware configured to recognize communication degradation associated with any of said communication entities.
9. The machine readable medium of claim 8 , wherein said middleware is further configured to switch communication among said logical communication entities.
