Dear Naresh,
this is a side effect caused by WMS tiled requests using the default
"raster" style on GeoServer.

In order to improve this, you should create a correct SLD[1] of type
RasterSymbolizer[2] compatible with your dataset, and upload it to
GeoServer.

You can also use advanced colormaps, like [3].
