The data forwarding by the GPSR
protocol can be made by two ways: greedy forwarding and perimeter forwarding.

As a repair strategy at local maxima, GPCR also uses perimeter routing strategy as in GPSR
. The assumption of always finding a node at junctions makes the protocol impractical at some point of time.
When combined with the GPSR
series repeaters, the entire system can be increased to support up to 32 total RF outputs from one GPS signal source.
The proposed FAGOR protocol is benchmarked against other three routing protocols: (1) DWSIGF, (2) GPSR
, and (3) QGOR (a QoS-aware GOR which provides routing service based on the end-to-end QoS metric ).
For the adaptive reconstruction scheme, (21) is solved by using GPSR
algorithm , and the transformation matrix [PSI] uses Daubechies orthogonal wavelet of 4 in length.
[l.sub.1]- magic algorithm in , the gradient projection for sparse reconstruction algorithm (GPSR
) in , and their variants also belong to the convex relaxation categories.
