1Length of stationary object
If data is transmitted through multiple hops in wireless sensor networks, then data can reach the sink from distant sensor nodes, but power consumption increases and transmission time increases
Solution Approach 1:
The data transmission path is segmented into multiple parallel paths from source to sink. Instead of using a single long-hop path that consumes excessive power, the invention divides the transmission into multiple shorter segments across different routes, allowing data to be distributed and transmitted through multiple sensor nodes simultaneously, thereby reducing overall power consumption while maintaining coverage range.
Solution Approach 2:
The invention transitions from a single-dimensional (single path) transmission model to a multi-dimensional (multiple paths) transmission model. By identifying and utilizing multiple paths through different sensor nodes, the system adds spatial diversity to the transmission, enabling simultaneous data flow through multiple routes which reduces both power consumption and transmission time while maintaining the same coverage range.
2Length of stationary object
If data is transmitted through multiple hops in wireless sensor networks, then data can reach the sink from distant sensor nodes, but transmission time increases due to multiple relay points
Solution Approach 1:
The transmission process is segmented into multiple parallel paths, allowing data to be divided and transmitted simultaneously through different routes. This segmentation enables concurrent transmission rather than sequential relay, significantly reducing the total transmission time while maintaining the ability to cover the same network distance.
Solution Approach 2:
The invention ensures continuous data flow through multiple active paths simultaneously. Instead of data waiting at each relay node in a single path, the continuous transmission across multiple parallel paths eliminates idle waiting time, maintaining constant data movement from source to sink and thereby reducing overall transmission time while preserving coverage range.
3Productivity
If multiple paths are used for data transmission, then power consumption and transmission time can be optimized, but routing complexity increases
Solution Approach 1:
The system performs preliminary identification of multiple viable paths from source to sink before actual data transmission begins. By pre-computing and storing these paths, the routing complexity is managed in advance, allowing the transmission phase to simply select from pre-validated routes, thereby reducing real-time computational complexity while maintaining high transmission efficiency through optimized path selection.
