Solution Overview

Problem

Conventional access methods for multimode user equipment in wireless sensor networks lead to unnecessary collisions, reducing spectral efficiency and sensor network density due to the mobile nature of user equipment and static location of sensor elements.

Innovation Solution

A coordinated access method where the multimode user equipment receives broadcasted wireless sensor network information, requests access information from a base station, and accesses the network using allocated access slots, reducing collisions and improving resource management through an enhanced MAC protocol.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional MAC protocol access method is used, then wireless sensor network elements can access the network, but unnecessary collisions occur between multimode user equipment and wireless sensor network, reducing spectral efficiency and sensor network density

Engineering Contradiction:

Improveaccess reliabilityVSAvoidspectral efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The access method is segmented into distinct phases: wireless sensor network information acquisition phase and wireless sensor network access phase. This segmentation allows different protocols to be applied at different stages, reducing collisions while maintaining access reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mobile data network base station acts as an intermediary that coordinates access between multimode user equipment and the wireless sensor network. The base station receives access requests, determines available access slots, and provides this information to the user equipment, thereby mediating the access process to reduce collisions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If conventional MAC protocol access method is used, then wireless sensor network elements can communicate, but collisions reduce sensor network density

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidsensor network density

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The user equipment acquires wireless sensor network information (including access slot allocations and cluster head identifiers) before attempting to access the network. This preliminary action allows the equipment to prepare appropriate access requests in advance, reducing collisions and improving the ability to maintain high sensor network density.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multimode user equipment accesses both mobile data network and wireless sensor network simultaneously, then mobility and large data transmission capability are combined, but energy consumption increases

Engineering Contradiction:

Improvenetwork access versatilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The access method uses periodic access slots that are pre-allocated and coordinated through the base station. Instead of continuous contention-based access, the multimode user equipment transmits data during designated periodic time slots, reducing energy consumption while maintaining the ability to access both networks.

Inventive Principle:

Principle #19Periodic action
