The various application in Wireless Sensor Networks fascinated towards minimal and secure data transmission. In this paper, VEDSDA protocol is proposed to achieve reduction of data redundancy, data length and providing security for data transmission. The VEDSDA protocol used compression technique to reduce data length which helps to utilize less energy consumption. The data compression technique involves leveling, encoding and decoding phases. Levelling phase converts data to logical data where as encoding phase compress the data size at the source node and decoding phase decompress the data size at the destination. The voronoi diagram concept is used to encrypt and decrypt aggregated data. Thus, VEDSDA protocol is compared with existing protocol and proves better enhancement.

无线传感器网络中的各种应用都着迷于最小化和安全的数据传输。本文提出了VEDSDA协议，以实现减少数据冗余、减少数据长度并为数据传输提供安全性。VEDSDA 协议使用压缩技术来减少数据长度，这有助于利用更少的能源消耗。数据压缩技术涉及调平、编码和解码阶段。调平阶段将数据转换为逻辑数据，其中编码阶段压缩源节点的数据大小，解码阶段解压缩目的地的数据大小。voronoi 图概念用于加密和解密聚合数据。因此，VEDSDA 协议与现有协议进行了比较，证明了更好的增强。
