Abstract The value of data to a company means that it must be protected. When comes safeguarding their local and worldwide databases, businesses face number challenges. To systematically review the literature highlight difficulties in establishing, implementing, maintaining secure databases. In order better understand database system problems, we did systematic mapping study (SMS). We’ve analyzed 100 research publications from different digital libraries found 20 issues after adopting...

Due to the energy resource restriction, sensor nodes drain out their power. Therefore routing mechanism among and sink need consider balanced utilization. Low-Energy Adaptive Clustering Hierarchy (LEACH) direct data communication from source cluster head sink, which results unbalanced consumption of heads CHs leads holes in network. For maximum network lifetime an Energy efficient Least Edge Computation protocol (ELEC) is proposed literature. The simulation show better performance ELEC as...

To minimize the communication overhead with help of optimal path selection in Wireless Sensor Network (WSN) routing protocols is challenging issue. Hierarchical optimizes energy utilization by distributing workload among different clusters. But many-to-one multi-hop hierarchical will result excessive expenditure near sink and leads to early exhaustion nodes. Due this hole problem can be caused around base station. Data routed along boundary nodes lead premature energy. This maximize size...
