Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for virtualized overlays in wireless networks face inefficiencies due to resource constraints and separation between upper and lower layers, resulting in significant time delays and high packet loss rates.
Innovation Solution
A cross-layer overlay searching technique is implemented, which uses network layer broadcasting to route packets efficiently, achieving a complexity of O(n) by mapping keys to unique virtual network addresses and broadcasting route requests, and a monitoring overlay to collect and provide network information, optimizing route finding and network condition awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hierarchical device networking model is used, then system positioning and roles are governed, but end-users' control over service delivery is limited
Solution Approach 1:
The patent segments the network into virtualized overlay networks that operate independently above the physical infrastructure. This allows end-users to create and control their own virtual networks with customized service delivery mechanisms without being constrained by the hierarchical positioning model of the underlying physical network.
Solution Approach 2:
The patent introduces a new dimension by implementing virtualized overlay networks that operate at a higher abstraction layer. This dimensional shift enables end-users to control service delivery through virtual network configurations without modifying the physical network hierarchy, thereby increasing adaptability while maintaining infrastructure stability.
2Adaptability or versatility
If virtualized overlay is implemented in wireless networks, then service delivery flexibility is improved, but resource constraints and layer separation cause significant time delays
Solution Approach 1:
The patent implements preliminary action by pre-establishing virtual network paths and service delivery configurations in the overlay network. This allows data to be routed efficiently through pre-defined virtual paths, reducing the time required for service delivery while maintaining the flexibility of virtualized networks.
Solution Approach 2:
The patent introduces an intermediary mechanism through the virtualized overlay network that mediates between the physical wireless network constraints and the service delivery requirements. This intermediary layer optimizes routing decisions to minimize delays while preserving service flexibility.
3Adaptability or versatility
If virtualized overlay is implemented in wireless networks, then service delivery flexibility is improved, but resource constraints and layer separation result in high packet loss rates
Solution Approach 1:
The patent implements feedback mechanisms in the virtualized overlay network that monitor network conditions and dynamically adjust service delivery paths. This feedback loop enables the system to respond to changing wireless network conditions, reducing packet loss while maintaining service flexibility through adaptive routing decisions.

AI summary
Methods and apparatus relating to a cross-layer approach for virtualized overlay on ad hoc networks are described. In one embodiment, a virtual address is used to search for a (key,value) pair in a virtual overlay. In an embodiment, a route request for a virtual address, corresponding to a key, is transmitted via a wireless network to one or more of a plurality of computing nodes forming a virtual search overlay and route reply for the virtual address is generated in response to the route request. Other embodiments are also described.
