1Object-generated harmful factors
If Spanning Tree Protocol is used for routing in MANET, then communication loops are prevented, but network reliability deteriorates due to unacceptable periods of interrupted communications while routing is rediscovered and disseminated to all routing nodes
Solution Approach 1:
The patent implements dynamic routing protocols that automatically adapt to topology changes in MANETs. The system continuously updates routing tables and redistributes routing information across the network, allowing rapid convergence after node movements or link failures without manual intervention, thus maintaining communication reliability while preventing loops through dynamic route calculation.
Solution Approach 2:
The system employs feedback mechanisms where routing nodes continuously exchange routing information and update their routing tables based on received updates. This feedback loop enables the network to automatically recover from topology changes, with nodes redistributing routing information to maintain connectivity and prevent communication loops through continuous network state awareness.
2Area of stationary object
If repeater device is used to extend wireless network, then network coverage is improved, but bandwidth is reduced by half due to sending and receiving on the same channel
Solution Approach 1:
The patent employs multiple radio transceivers operating on different channels or frequencies to extend network coverage. By adding the frequency dimension, the system allows simultaneous transmission and reception on different channels, eliminating the bandwidth halving problem of single-channel repeaters while maintaining extended coverage area.
3Ease of operation
If mobile nodes are deployed in MANET, then network deployment ease and speed are improved, but interference increases due to sharing common radio frequencies among neighboring nodes
Solution Approach 1:
The system uses multiple radio transceivers that can operate on different channels or frequencies simultaneously. This adds the frequency dimension to spatial separation, allowing mobile nodes to communicate on multiple channels and reducing interference by distributing traffic across different frequency resources while maintaining deployment ease.
Solution Approach 2:
The patent implements dynamic channel selection and frequency hopping mechanisms that change operating parameters based on network conditions. Mobile nodes can switch between channels to avoid interference, and the system adapts transmission parameters such as power levels and modulation schemes to optimize performance while maintaining ease of deployment.
