Multihop Paging in Peer-to-Peer Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional peer-to-peer wireless communication networks face inefficiencies in paging disparate peers, leading to inefficient power usage and asynchronous communication challenges, as they typically operate without a synchronized clock reference, making it difficult to initiate direct communication and utilize wireless spectrum effectively.
Innovation Solution
The implementation of a method and apparatus that enables indirect paging in a peer-to-peer network through a series of direct peer-to-peer messages, where a first wireless terminal receives a paging message and determines it is designated for a second peer, transmitting a related message to facilitate multihop paging, allowing peers to communicate directly without infrastructure base stations and synchronize communication intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional peer-to-peer networks operate in an asynchronous manner without synchronized clock reference, then device complexity is reduced and ease of operation is improved, but productivity deteriorates due to inefficient paging and communication initiation
Solution Approach 1:
The patent implements preliminary synchronization of clock references among peers before asynchronous operation begins. This preliminary action establishes a common time base that enables efficient paging and communication initiation, resolving the contradiction by preparing the system state in advance without adding complexity to the ongoing asynchronous operations.
Solution Approach 2:
The patent introduces a synchronization mechanism as an intermediary that coordinates time references among peers. This intermediary layer enables efficient paging by establishing synchronized intervals without requiring all peers to continuously maintain complex synchronization protocols during their asynchronous operations, thus improving productivity while preserving ease of operation.
2Device complexity
If peers transmit paging messages directly without multihop routing, then device complexity is reduced, but productivity deteriorates when peers are out of direct communication range
Solution Approach 1:
The patent segments the paging message transmission process into multiple hops, where each peer forwards the paging message to another peer within its range. This segmentation enables the paging message to traverse across large distances by breaking the transmission path into manageable segments, improving productivity for distant peers while maintaining relatively simple direct peer-to-peer transmission mechanisms at each hop.
Solution Approach 2:
The patent extends the paging mechanism from direct one-to-one communication to a multi-dimensional relay approach where paging messages can be routed through multiple intermediate peers. This dimensional change in communication topology enables peers to reach each other indirectly through a series of direct connections, improving productivity for out-of-range peers without significantly increasing the complexity of individual peer implementations.
3Area of stationary object
If wireless spectrum is allocated for wide area network cellular communication, then coverage area is improved, but loss of energy increases due to inefficient spectrum utilization in given geographic locations or time intervals
Solution Approach 1:
The patent implements dynamic adaptation of communication parameters including transmission power and spectrum allocation based on real-time conditions. By making these parameters dynamic rather than static, the system can optimize energy usage by adjusting transmission levels to actual needs, reducing energy loss in specific geographic locations or time intervals while maintaining comprehensive coverage area through flexible resource allocation.

AI summary
Systems and methodologies are described that facilitate indirectly paging a peer in a peer-to-peer communication network via a series of direct peer-to-peer pages. Paging messages may be communicated directly between peers. Moreover, a paging message communicated from a first peer to a second peer may be further routed to a third peer. For example, the paging message may include information (e.g., an identifier associated with an ultimate destination) utilized to effectuate multihop paging; thus, upon obtaining the paging message, a peer may forward the paging message based upon such information.
