The rapid deployment of wireless sensor network helps to form a network in varieties of applications. For example, WSN can be used to perform data collection in war field. However the qualities of service of WSN depending on various operations like routing and scheduling. Numerous routing protocols are being addressed to solve the scheduling problems in wireless sensor networks. But they suffer with poor QoS values. To address these issues, an energy efficient multi attribute time slot scheduling (MATSS) algorithm is proposed in this paper. The algorithm is focused to extend the lifetime of sensor nodes with multi part dynamic routing (MPDR) neighbour conditions and previous time slot conditions. Based on both the values the node has been scheduled as sleep/wakeup mode and this will be performed for each time slot. The selection of node is performed according to the condition of neighbour nodes and energy parameter by sharing the information between them. The MPDR routing performs both shortest path routing and energy efficient longer route to maximize the network lifetime. Also it aims to maximize the throughput ratio. In the beginning the nodes are scheduled according to the protocol has been implemented in Network Simulator (NS-2) and It has been evaluated with different number of nodes. The MATSS algorithm schedules the node states based on previous state and neighbour conditions, this improves the throughput by 7.6% and reduces the latency up to 4 ms.
