Packing and placement are two crucial stages for FPGA realization. In the design flow, the basic logic units, such as look-up-tables (LUTs) and flip-flops (FFs), have to be merged into configurable logic blocks (CLBs) before placement. How the basic logic blocks are clustered in the packing stage has a great impact on the placement quality. This work presents an analytical placement framework for...
Energy efficiency is an important criterion for routing algorithms in the wireless sensor network.

Since sensor nodes are energy constrained as they have limited power resources, they turn off their energy earlier. So, it will be so hard and so expensive to change or recharge their batteries from one time to another especially for a large scale networks. Therefore, prolonging their lifetime is a key issue that should be highly considered. As a solution for this problem is to manage intelligently...
